Description
Technical field
The present invention relates to the medical machinery field, particularly a kind of gripper jaw for the solidifying cutter of heat.
Background technology
Minimally Invasive Surgery, be the operation that utilizes the modern medical equipment such as peritoneoscope, thoracoscope and relevant device to carry out, and has that wound is little, pain light, recover fast superiority.Along with the progress of technology, Minimally Invasive Surgery has been deep into operating various field.
The solidifying cutter of heat are one of most important apparatuses of thermal weld technological system in Minimally Invasive Surgery, gripper jaw is one of vitals of the solidifying cutter of heat, inhomogeneous and the deformation of the gripper jaw that uses of present stage heated filament stress when work, the a large amount of conduction to corpus unguis of heated filament energy meeting when prolonged operations, make the temperature of corpus unguis higher, when serious, can scald in-vivo tissue, and the gripper jaw complex structure of present stage use, bearing capacity is little, and manufacture difficulty is large.Through extensively retrieval, not yet find comparatively desirable technical scheme.
Summary of the invention
The gripper jaw bearing capacity the objective of the invention is in order to solve the solidifying cutter of present stage heat is little, and manufacture difficulty is large, and during operation, the temperature of corpus unguis height is easily scalded the shortcomings such as in-vivo tissue, and a kind of gripper jaw for the solidifying cutter of heat proposed.
To achieve these goals, the present invention has adopted following technical scheme:
A kind of gripper jaw for the solidifying cutter of heat, comprise corpus unguis, be provided with heating wire on corpus unguis, be provided with the pawl shell in the corpus unguis outside, it is characterized in that: the medial surface in the rear end of corpus unguis is provided with a contiguous block, be provided with a pin-and-hole at contiguous block, lateral surface in the rear end of corpus unguis is provided with an attachment strap, at the medial surface of the retained part of the corpus unguis sealing coat that is connected, at the medial surface of the sealing coat heating wire that is connected, at corpus unguis, the coated outside pawl shell of sealing coat and heating wire matable assembly, medial surface at the pawl shell is provided with opening, in opening and heating wire corresponding matching.
On the basis of technique scheme, following further technical scheme can be arranged:
Described corpus unguis and sealing coat front end are provided with the fluting cooperatively interacted, temperature sensor is connected in fluting, temperature sensor is arranged in the pawl shell, and temperature sensor contacts cooperation with heating wire, and temperature sensor is connected with the electric-controlled box of the solidifying cutter of heat by wire.
Medial surface at the retained part of described corpus unguis is provided with groove, lateral surface at described sealing coat is provided with boss, described boss and groove corresponding matching, be provided with a slot to make way on the medial surface of sealing coat, the heating wire that is connected in slot to make way, sealing coat and heating wire are sintered together.
Clamping part at described corpus unguis has formed the structure of reinforcement in the both sides of groove, strengthened the rigidity of gripper jaw.Described pawl shell is made of plastic, and the part of heating wire is exposed from the opening of pawl shell, and when two gripper jaws coordinate, heating wire can be in contact with one another and conduct electricity, and the pawl shell has played good insulating effect.
The rear end of described two corpus unguis that match all is connected with the stay pipe of the solidifying cutter of heat and the front end of outer tube, an outer tube of front side socket of described stay pipe, and stay pipe can slide within the outer tube.Be symmetrical arranged two square mouths of taking at the front end of stay pipe, also be provided with the rectangular chute of two symmetries at the front end of stay pipe, described two chutes run through that line takes mouthful with two to run through line mutually vertical, be provided with the fixing hole of two symmetries at the outer tube front end, each fixing hole and corresponding chute corresponding matching.
The contiguous block of described two corpus unguis, one is the tenon mouth structure, another is tenon structure, also be provided with the pin-and-hole of corresponding matching on two contiguous blocks, two corpus unguis match 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 the 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, and described fitting pin two ends all are fixed in the pin sky of outer tube.
Ceramic material or the high temperature resistant hard plastics such as zirconium oxide that described sealing coat is less with heat conductivity, its effect is: make the stress of heated filament when state has been answered in clamping more all even minimizing heated filament energy to the conduction of corpus unguis.
Minimum filament or laminar metal (or quasiconductor) thermal resistance sensor of thermal inertia for described temperature sensor, press close to that heated filament is placed and with the heated filament electric insulation.This temperature sensor is as hot-wire temperature's measuring cell, the heated filament operating temperature is measured in real time, coordinate Conditioning Circuits of Sensor, heated filament operating temperature signal is offered to the electric-controlled box of the solidifying cutter of heat, electric-controlled box carries out real-time closed loop control by the thermoregulation algorithm to the heated filament operating temperature.During operation, can on liquid crystal touch panel, to heated filament, carry out accurate temperature setting, thoroughly solve while being controlled by rule of thumb by the operator and the too high impact on surgical effect of hot-wire temperature produced, 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 and rotates around fitting pin, thereby realize the opening and closing of gripper jaw, circuit turn-on when gripper jaw is closed, can be performed the operation.
The invention has the advantages that: this device is easily manufactured, when state has been answered in clamping, heated filament has answered evenly, during work, the heat of corpus unguis is little, be conducive to the heated filament operating temperature is carried out to real-time closed loop control, the temperature of heated filament arranges precisely, gripper jaw is heated evenly, has stopped the generation of the phenomenon of overheated fracture of wire.
