Abstract
Many advantages, such as endoscope-assistant surgery is small with its operation wound, postoperative pain is light, the hospital stays is short and cosmetic result is good becomes increasingly popular in worldwide.Medical operation device is made of two parts, the handle of the front end group and operation front end group of different function.It needs to carry out handle and front-end operations group to separate design in structure, be connect with functor by connecting rod, but how to ensure that functor connecting rod is connected with functor in the course of surgery and energy relative motion is existing problem after separating.In order to solve the problems, such as that functor connecting rod connects simultaneously energy relative motion with functor in the course of surgery, the utility model provides a kind of medical operation device ejector sleeve, the ejector sleeve includes central tube and insulating layer, the central tube is a hollow tubular structure, one end is provided with the bindiny mechanism with runner, chamfering is provided at the end face inner bore of the other end, the insulating layer is set with or is painted on the tube outer surface of center.
Description
Technical field
The utility model is related to arrive medical operation device field, it is related specifically to a kind of medical operation device ejector sleeve.
Background technology
Many advantages, such as endoscope-assistant surgery is small with its operation wound, postoperative pain is light, the hospital stays is short and cosmetic result is good
It is become increasingly popular in worldwide.Medical operation device is made of two parts, the front end group of different function and operation front end
The handle of group.Presently used material is medical plastic, easy to wear, and easy overhauling after plastic products abrasion leads to the residual of germ
It stays.Structure upper handle is integrated with front-end operations group, not easy to remove, and remaining germ of inner wall etc. is not easy thoroughly to be killed.It is aobvious
So, it needs to carry out handle and front-end operations group to separate design in structure, be connect with functor by connecting rod, but separate
How to ensure that functor connecting rod is connected with functor in the course of surgery and energy relative motion is existing problem afterwards.
Utility model content
In order to solve the problems, such as that functor connecting rod connects simultaneously energy relative motion, this practicality with functor in the course of surgery
It is novel to provide a kind of medical operation device ejector sleeve.
A kind of medical operation device ejector sleeve of the utility model, the ejector sleeve include central tube and insulating layer, and the central tube is
One hollow tubular structure, one end are provided with the bindiny mechanism with runner, and chamfering is provided at the end face inner bore of the other end, described
Insulating layer is set with or is painted on the tube outer surface of center.
Further, the bindiny mechanism includes screw thread, buckle, riveting or pin joint mechanism.
Further, the central tube is stainless steel material, or is plastics, nylon, Carbon fibe or high molecular material
In a kind of and a variety of mixing material.
Further, the chamfering is fillet or oblique angle.
A kind of advantageous effects of medical operation device ejector sleeve of the utility model are：The ejector sleeve includes central tube and insulation
Layer, for the ease of the use of ejector sleeve, the insulating layer is set with or is painted on the tube outer surface of center, and the central tube is one hollow
Tubular structure, one end is provided with the bindiny mechanism with runner, and to fix ejector sleeve, surgical instrument front-end functionality part is set with connecting rod
It sets in ejector sleeve, using the relative movement of center inside pipe wall limitation function part and functor connecting rod, while central tube is also work(
The junction of energy part and functor connecting rod provides protection, for the ease of the movement of functor, the end face of the central tube other end
Chamfering is provided at endoporus, solving functor connecting rod in the course of surgery with this connects simultaneously energy relative motion with functor
Problem prevents functor from falling off in the course of surgery.
Description of the drawings
Attached drawing 1 is a kind of medical operation device ejector sleeve of the utility model and runner connection diagram.
Attached drawing 2 is the schematic cross-sectional view that a kind of medical operation device ejector sleeve interconnecting piece of the utility model is bolt.
Attached drawing 3 is the connection signal that a kind of medical operation device ejector sleeve interconnecting piece of the utility model is rotary buckle connection
Figure.
Attached drawing 4 is that a kind of medical operation device ejector sleeve of the utility model is set with functor and the schematic diagram of connecting rod.
In figure：（1）Central tube,（101）Ejector sleeve chamfering,（102）Bindiny mechanism,（2）Insulating layer,（3）Steering fixture,
（4）Medical operation device handle,（5）Functor,（6）Functor connecting rod.
Specific implementation mode
A kind of medical operation device ejector sleeve of the utility model is made further in the following with reference to the drawings and specific embodiments
It is bright.
Attached drawing 1 is a kind of medical operation device ejector sleeve of the utility model and runner connection diagram, and attached drawing 2 is that this practicality is new
A kind of medical operation device ejector sleeve interconnecting piece of type is the schematic cross-sectional view of bolt, and attached drawing 3 is a kind of medical operation of the utility model
Instrument ejector sleeve interconnecting piece is the connection diagram of rotary buckle connection, and attached drawing 4 is that a kind of medical operation device of the utility model pushes away
Pipe sleeve is equipped with the schematic diagram of functor and connecting rod.As seen from the figure, a kind of endoscope-assistant surgery instrument ejector sleeve of the utility model, the ejector sleeve
Including central tube（1）And insulating layer（2）, the central tube（1）For a hollow tubular structure, one end is provided with the company with runner
Connection mechanism（102）, chamfering is provided at the end face inner bore of the other end（101）, the insulating layer（2）It is set with or is painted on central tube
（1）On outer surface.
A kind of medical operation device ejector sleeve of the utility model is in actual use, described exhausted for the ease of the use of ejector sleeve
Edge layer（2）It is set with or is painted on central tube（1）On outer surface, insulating layer is used in the present embodiment（2）It is sleeved on central tube（1）
On outer surface, in another embodiment, it is painted on the tube outer surface of center using insulating layer, the central tube（1）It is hollow for one
Tubular structure, one end is provided with the bindiny mechanism with runner（102）, to fix ejector sleeve, surgical instrument front-end functionality part and company
Extension bar is arranged in ejector sleeve, utilizes central tube（1）The relative movement of inner wall limitation function part and functor connecting rod, while center
Pipe（1）Also the junction for functor and functor connecting rod provides protection, for the ease of the movement of functor, central tube
（1）It is provided with chamfering at the end face inner bore of the other end, functor connecting rod in the course of surgery is solved with this and functor connects
The problem of connecing simultaneously energy relative motion, prevents functor from falling off in the course of surgery.
Further, in order to facilitate the connection and dismounting of ejector sleeve and runner, the bindiny mechanism includes screw thread, buckle, riveting
