Abstract
The invention relates to an antenna expander. The antenna expander comprises a clamp rod, a clamp head bending adjusting rod and a clamp head expansion degree adjusting rod. The clamp head bending adjusting rod and the clamp head expansion degree adjusting rod are located in the clamp rod. The front end of the clamp head bending adjusting rod is connected with the blade through a bendable clamp base. The front end of the clamp head expansion degree adjusting rod is connected with the blade through a transmission rod. The blade is located at the front end of the clamp rod, and the rear end of the clamp rod and a handle connector are connected and fixed. The rear end of the clamp head bending adjusting rod is linked with a clamp head bending adjusting nut. The rear end of the clamp head expansion degree adjusting rod is linked with a blade adjusting nut. An adjusting shaft is connected between the clamp head expansion degree adjusting rod and the transmission rod. A blade adjusting transmission rod is connected between the clamp head expansion degree adjusting rod and the blade adjusting nut. The antenna expander has the advantages that design is novel, operation is convenient and safe, the organization range of a bracket is effectively widened, and it is guaranteed that the operation success rate is increased.
Description
Technical field
The invention belongs to technical field of medical instruments, particularly relate to a kind of main antenna dilator working the bracket effect of supporting tissue when performing the operation.
Background technology
The bracket effect of supporting tissue (large intestine, heart, liver etc.) when antenna dilator mainly plays operation, existing antenna dilator asks SANYE, five leaf pincers etc., because anterior leaflet is many, cause frontal area to become large, and apparatus rear portion area is little, so just causes the unbalance of organizing of bracketing, what run-off the straight made bracketing organizes landing, easily flee from the working position needing operation during operation, can not to ensure, stable bracketing tissue, easily the enforcement of obstruction surgical work.
Summary of the invention
The object of the invention is to overcome the deficiency that prior art exists, and a kind of scope of organization that is easy to operate, safe, effectively expansion bracketing is provided, guarantees the antenna dilator that success rate of operation improves.
The object of the invention is to have come by following technical solution.This antenna dilator, comprise claw beam, binding clip camber adjusting rod, binding clip opening width adjusting rod, described binding clip camber adjusting rod, binding clip opening width adjusting rod are positioned at claw beam, the front end of binding clip camber adjusting rod is connected with blade by bendable clamp block, and the front end of binding clip opening width adjusting rod is connected with blade by drive link; This blade is positioned at the front end of claw beam, and rear end and the handle joint of claw beam are connected to a fixed; Rear end and the binding clip camber adjusting nut of described binding clip camber adjusting rod are connected, and the rear end of described binding clip opening width adjusting rod and blade adjustments nut coupled thereto move.Be connected with regulating shaft between described binding clip opening width adjusting rod and drive link, between binding clip opening width adjusting rod and blade adjustments nut, be connected with blade adjustments drive link.
As preferably, described blade forms the blade of flexible shape by some pieces of holder combination.
Beneficial effect of the present invention is: this product design is novel, the scope of organization that is easy to operate, safe, effectively expansion bracketing, guarantees that success rate of operation improves; Apparatus has stable bracketing tissue and expands the angle of the bracketing scope of organization and up-down adjustment bracketing tissue, and the visual range providing endoscope regulates random, is that doctor implements the useful tool of operation to pathological tissues.

Label in accompanying drawing is respectively: 1, blade; 2, drive link; 3, bendable clamp block; 4, claw beam; 5, handle joint; 6, binding clip camber adjusting nut; 7, blade adjustments drive link; 8, blade adjustments nut; 9, regulating shaft; 10, binding clip camber adjusting rod; 11, binding clip opening width adjusting rod.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed introduction is done to the present invention: as shown in accompanying drawing 1,2, the present invention includes claw beam 4, binding clip camber adjusting rod 10, binding clip opening width adjusting rod 11, described binding clip camber adjusting rod 10, binding clip opening width adjusting rod 11 are positioned at claw beam 4, the front end of binding clip camber adjusting rod 10 is connected with blade 1 by bendable clamp block 3, and the front end of binding clip opening width adjusting rod 11 is connected with blade 1 by drive link 2; This blade 1 is positioned at the front end of claw beam 4, and rear end and the handle joint 5 of claw beam 4 are connected to a fixed; Rear end and the binding clip camber adjusting nut 6 of described binding clip camber adjusting rod 10 are connected, and rear end and the blade adjustments nut 8 of described binding clip opening width adjusting rod 11 are connected.
Described binding clip camber adjusting nut 6 linkage regulates binding clip camber adjusting rod 10 angle, for regulate binding clip camber can wider, up slowly regulate the tissue such as heart, liver holding up bracketing in dilator, play expanded scope, larger operative space be provided, the visual visual field degree of convenient operation steering range and endoscope.
Described blade adjustments nut 8 linkage blade adjustments drive link 7 regulates the opening angle size of binding clip blade 1 by binding clip opening width adjusting rod 11, and (tissue volume of bracketing is large, can expand by adjusting vane 1 opening angle; The tissue volume of bracketing is little, and what can close that blade 1 reduces bracketing organizes area).
Be connected with regulating shaft 9 between described binding clip opening width adjusting rod 11 and drive link 2, this regulating shaft 9 moves forward and backward to promote drive link 2, and to shrink, open the tissue of required distraction angle and picking-up when medical worker operates when making blade 1 reach operation how many; Blade adjustments drive link 7 is connected with between binding clip opening width adjusting rod 11 and blade adjustments nut 8.
Described blade 1 is formed the blade of flexible shape by some pieces of holder combination, blade 1 can close and open, close closed after diminish and conveniently put into perforator, enlarged-area can be strutted after putting into, 180 ° of straight lines can be set level into when strutting, width struts to more than 60mm, and length is fixed as 10mm, plays the bracketing effect of wider bracketing tissue (large intestine, heart, liver etc.); In the middle of thoracic cavity, abdominal operation, heart, liver and lung can be held up simultaneously create larger working place to operation.
Antenna dilator has parallelogram mechanical drive principle; Effectively can ensure the opening angle of the blade 1 of binding clip, can as required bracketing organize size to regulate blade 1 size of binding clip, play and be similar to the effect that people holds bracketing tissue in hands, the blade 1 of the binding clip held up can up-down adjustment, facilitates doctor more conveniently can see pathological tissues implementation to performing the operation clearly from multiple angles by internal control mirror; During the blade 1 of closed binding clip, the pole of a minimum diameter can be formed as, antenna dilator can be made to narrow down to body that minimum area puts into patient, there is several functions.
The present invention is not limited to above-mentioned embodiment, no matter do any change, every employing structural design provided by the present invention on its shape or material are formed, is all one distortion of the present invention, all should thinks within scope.
