Description
Technical field
The present invention relates to medical machinery field, particularly a kind of gripper jaw for heat setting cutter.
Background technology
Minimally Invasive Surgery is the operation utilizing the modern medical equipment such as peritoneoscope, thoracoscope and relevant device to carry out, and has that wound is little, pain is light, recover fast superiority.Along with the progress of technology, Minimally Invasive Surgery has been deep into operating various field.
Heat setting cutter are one of most important apparatuses of thermal weld technological system in Minimally Invasive Surgery, gripper jaw is one of vitals of heat setting cutter, the gripper jaw that present stage uses the operationally uneven and deformation of heated filament stress, when prolonged operations, heated filament energy can in a large number to the conduction of corpus unguis, make the temperature of corpus unguis higher, time serious, can in-vivo tissue be scalded, and the gripper jaw complex structure that present stage uses, bearing capacity is little, and manufacture difficulty is large.Through extensively retrieval, not yet find ideal technical scheme.
Summary of the invention
The gripper jaw bearing capacity that the object of the invention is to solve present stage heat setting cutter is little, and manufacture difficulty is large, and during operation, the temperature of corpus unguis is high easily scalds the shortcomings such as in-vivo tissue, and a kind of gripper jaw for heat setting cutter proposed.
To achieve these goals, present invention employs following technical scheme:
A kind of gripper jaw for heat setting cutter, comprise corpus unguis, corpus unguis is provided with heating wire, pawl shell is provided with outside corpus unguis, it is characterized in that: be provided with a contiguous block at the medial surface of the rear end of corpus unguis, a pin-and-hole is provided with at contiguous block, an attachment strap is provided with at the lateral surface of the rear end of corpus unguis, to be connected sealing coat at the medial surface of the retained part of corpus unguis, to be connected a heating wire at the medial surface of sealing coat, at corpus unguis, the outside parcel pawl shell of sealing coat and heating wire matable assembly, opening is provided with at the medial surface of pawl shell, in opening and heating wire corresponding matching.
On the basis of technique scheme, following further technical scheme can be had:
Described corpus unguis and sealing coat front end are provided with the fluting cooperatively interacted, be connected temperature sensor in fluting, temperature sensor is arranged in pawl shell, and temperature sensor contacts with heating wire and coordinates, and temperature sensor is connected by the electric-controlled box of wire with heat setting cutter.
Groove is provided with at the medial surface of the retained part of described corpus unguis, boss is provided with at the lateral surface of described sealing coat, described boss and groove corresponding matching, the medial surface of sealing coat is provided with a slot to make way, be connected a heating wire in slot to make way, and sealing coat and heating wire are sintered together.
Define the structure of reinforcement at the clamping part of described corpus unguis in the both sides of groove, enhance the rigidity of gripper jaw.Described pawl shell is made of plastic, and a part for heating wire is exposed from the opening of pawl shell, and when two gripper jaws coordinate, heating wire can contact with each other and conduct electricity, and pawl shell serves good insulating effect.
The rear end of match two described corpus unguis is all connected with the stay pipe of heat setting cutter and the front end of outer tube, and the front side of described stay pipe is socketed an outer tube, and stay pipe can slide within the outer tube.Be symmetrical arranged two in the front end of stay pipe and square take mouth, two symmetrical rectangular chutes are also provided with in the front end of stay pipe, two described chutes run through line with two take mouth to run through line mutually vertical, two symmetrical fixing hole, each fixing hole and corresponding chute corresponding matching are provided with in outer tube front end.
The contiguous block of two described corpus unguis, one is tenon mouth structure, another is tenon structure, two contiguous blocks are also provided with the pin-and-hole of corresponding matching, two corpus unguis are matched by tenon mouth and tenon, after two corpus unguis coordinate, their rear side is arranged in stay pipe, each attachment strap of corpus unguis is connected with corresponding mouth of taking respectively, fitting pin is successively through fixing hole, chute and pin-and-hole, outer tube, stay pipe and two corpus unguis are linked together, described fitting pin two ends are all fixed in the pin sky of outer tube.
Ceramic material or the high temperature resistant hard plastics such as the zirconium oxide that described sealing coat heat conductivity is less, its effect is: make heated filament at the stress clamped when having answered state evenly and reduce the conduction of heated filament energy to corpus unguis.
The filament that described temperature sensor thermal inertia is minimum or platelet-like metal (or quasiconductor) thermal resistance sensor, press close to heated filament place and with heated filament electric insulation.This temperature sensor is as the measuring cell of hot-wire temperature, heated filament operating temperature is measured in real time, coordinate Conditioning Circuits of Sensor, heated filament operating tempera-ture signal is supplied to the electric-controlled box of heat setting cutter, electric-controlled box regulates algorithm to carry out real-time closed loop control to heated filament operating temperature by temperature.During operation, on liquid crystal touch panel, accurate temperature setting can be carried out to heated filament, thoroughly solve the too high impact on surgical effect of the hot-wire temperature produced when being controlled by rule of thumb by operator, also stop the phenomenon of overheated fracture of wire.
Because stay pipe and outer tube can relative slidings, when stay pipe moves, because two gripper jaws are fixed on outer tube by fitting pin, utilize the cooperation of hasp and attachment strap, stay pipe drives two gripper jaws to rotate around fitting pin, thus realize the opening and closing of gripper jaw, the circuit turn-on when gripper jaw closes, can perform the operation.
The invention has the advantages that: this device is easily manufactured, clamp answered state time heated filament answer evenly, during work, the heat of corpus unguis is little, be conducive to carrying out real-time closed loop control to heated filament operating temperature, the temperature of heated filament arranges precisely, gripper jaw is heated evenly, has stopped the generation of the phenomenon of overheated fracture of wire.
