Abstract

The utility model relates to a holder for laparoscope operations. The lower end of a sleeve pipe (1) is provided with a bevel pricking needle, and the upper end of the sleeve pipe (1) is provided with a positioning sleeve (3) which is matched with a gland (5). A sealing sleeve (4) is arranged in the gland (5). The lower section of a guide rod (6) is sheathed in the sleeve pipe (1), and the upper section is upwards extended to be penetrated through the positioning sleeve (3), the sealing sleeve (4) and the gland (5) to protrude to the upper surface of the gland (5). A handle (7) is arranged. An outer expansion type elastic sleeve ring (2) which is connected and fixed to the lower end of the guide rod (6) is arranged in the sleeve pipe (1). The utility model has the advantages of reasonable design, simple structure, easy fabrication, convenient operation, equalising and lasting traction force, and ideal effect. The traction direction and the tensile force can be adjusted according to operation needs.

Description

Laparoscopic surgery is controlled device

Technical field

This utility model relates to a kind of medical apparatus and instruments, and particularly a kind of laparoscopic surgery is controlled device.

Background technology

In laparoscopic surgery, to use usually and control device, cooperate operating theater instruments to insert the intraperitoneal operation that undergos surgery by perforator.Control device and mainly be and be used for adjusting or the direction at fixing operation position, so that operation technique.For example utilize three hole methods when handling appendix root, adopt titanium folder or silk thread ligation mostly.The titanium folder is relatively more expensive, and can stay metallic foreign body in the postoperative body, to total within some scruple of many patients.During with silk thread ligation appendix root, can't fix because of the vermiform appendix position, lack drawing tension again, its root exposes often not good, is difficult in satisfied position ligation.

And for swelling obviously, during the serious vermiform appendix of gangrene, bonding, adopt the nipper traction to hold, slippage had easily both influenced appearing of art open country, and the danger that causes damage of vermiform appendix wall and break-through vermiform appendix chamber is arranged again.Not only delay operating time, and increased the possibility that causes damage and pollute the abdominal cavity.Therefore the utmost point need provide a kind of and can adjust lead flexibly at present, and draws the persistent device of controlling of balancing in power.

Summary of the invention

The purpose of this utility model be to overcome the shortcoming of above-mentioned prior art and provide a kind of can according to the operation needs adjust flexibly lead, clamping firmly, the traction persistent laparoscopic tissue of balancing in power controls device.

The purpose of this utility model can realize by following technical measures: originally control device and be provided with sleeve pipe, guide post, the sleeve pipe lower end is the inclined-plane pricker, the lower end, inclined-plane is sharp, be used for puncture, telescopic upper end is provided with positioning sleeve, being provided with gland above the positioning sleeve is mated, in gland, be equiped with sealing shroud, compress by gland, localized accuracy in the time of can guaranteeing that guide post moves up and down, the guide post hypomere is sleeved in the sleeve pipe, and epimere extends up through positioning sleeve, sealing shroud, gland reaches above the gland, the guide post upper end is provided with handle, guide post can move up and down and rotate, and opens formula elastic force lasso outside being provided with in sleeve pipe, is bent into annular shape, elastic force lasso upper end is fastened on the guide post lower end, forms to have outside open spring element.When promoting guide post downwards, the elastic force lasso can stretch out downwards outside the sleeve pipe, and the elastic force lasso opens, when upwards spurring guide post, in the oppressed recoverable sleeve pipe of elastic force lasso.

This utility model is reasonable in design, can adjust lead and tension force according to the operation needs, operative site is exposed more and is easy to observe, and is convenient to operation technique, shortens operating time greatly; Its clamping is firm, and it is lasting that traction is balanced in power, can slippage, avoided influencing appearing of art open country.It applicable to peritoneoscope need resection organization traction, appear, operation such as hemostasis.As appendectomy, cholecystectomy, laparoscopic appendectomy, splenectomy, radical resection of rectal carcinoma, small intestinal, colectomy anastomosis, ovarian tumor excision, salpingotomy, hysterectomy etc.It is simple in structure, makes easily, and is easy to use, satisfactory for result.

Description of drawings

Fig. 1 is a structure chart of the present utility model;

Fig. 2 is a user mode reference diagram of the present utility model.

The specific embodiment

With reference to Fig. 1, originally controlling device has sleeve pipe [1], and sleeve pipe [1] adopts stainless steel material to make, and sleeve pipe [1] lower end is the inclined-plane pricker, the lower end, inclined-plane is sharp, be used for puncture, the upper end of sleeve pipe [1] is provided with positioning sleeve [3], has gland [5] to be mated above the positioning sleeve [3], gland [5] cooperates with the external screw thread that positioning sleeve [3] is provided with by female thread, in gland [5], be provided with sealing shroud [4], press, can guarantee guide post [6] localized accuracy when moving up and down by gland [5].Guide post [6] hypomere is sleeved in the sleeve pipe [1], epimere extends up through positioning sleeve [3], sealing shroud [4], gland [5] and reaches above the gland [5], guide post [6] upper end is provided with handle [7], be provided with the outer formula elastic force lasso [2] of opening in the sleeve pipe [1], after the bending, form annular shape, elastic force lasso [2] upper end two joints are weldingly fixed on guide post [6] lower end, form to have outside open spring element.Elastic force lasso [2], guide post [6] are made for rustless steel steel material.

During use, as carry out vermiform appendix and cut near operation, upwards spur guide post [4] with in elastic force lasso [2] the income sleeve pipe [1] by handle [7] earlier, select the abdominal cavity avascular area, the position, abdominal cavity of corresponding surgery location, under peritoneoscope monitors, thorn by sleeve pipe [1] lower end is needled into the abdominal cavity, promote guide post [4] downwards, elastic force lasso [2] can stretch out sleeve pipe [1] lower end down, elastic force lasso [2] is in open configuration at this moment, see Fig. 2, cooperate operating theater instruments such as clamp again, the vermiform appendix afterbody is drawn in the elastic force lasso [2], when upwards spurring guide post [6] again, tighten up elastic force lasso [2] and can control vermiform appendix, and can adjust lead and tension force as required, processing undergos surgery.Behind the EO, unclamp elastic force lasso [2], take off vermiform appendix, upwards spur guide post [4] elastic force lasso [2] is regained in the sleeve pipe [1], transfer to then and originally control device and get final product.

Claims

1, a kind of laparoscopic surgery is controlled device, sleeve pipe [1] is arranged, guide post [6], sleeve pipe [1] lower end is the inclined-plane pricker, the upper end that it is characterized in that sleeve pipe [1] is provided with positioning sleeve [3], being provided with gland [5] above the positioning sleeve [3] is mated, in gland [5], be equiped with sealing shroud [4], guide post [6] hypomere is sleeved in the sleeve pipe [1], epimere extends up through positioning sleeve [3], sealing shroud [4], gland [5] reaches above the gland [5], guide post [6] upper end is provided with handle [7], open formula elastic force lasso [2] outside being provided with in sleeve pipe [1], elastic force lasso [2] upper end is fastened on guide post [6] lower end, forms to have outside open spring element.
