Description

A kind of nail kit component reducing percussion force

Technical field

The utility model relates to surgical stapling medical instruments, more particularly to a kind of nail kit component that can reduce percussion force.

Background technique

The working principle of stapler is identical as stapler, i.e., into tissue the percussion staple that intermeshes of implantation to organize into Row stapling.When carrying out anastomosis operation, anastomat nail storehouse position is adjusted first, is kept nail bin and tissue to be anastomosed vertical, is kept Section is smooth, then compressed tissue 10-15 seconds, finally opens insurance, holds firing handle or trigger shaft, completes percussion.It coincide The closure of the cutting of device and staple is generally by distally pushing I-shaped push broach bar to complete: in push broach bar distal movement process In, the cutter positioned at push broach bar distal end are by tissue dissection；Staple is successively ejected, and across being sewn tissue, and is squeezed in nail anvil The molding of " B " word is completed in pressure.During stapler percussion, since the operation of percussion force ambassador's stapler is not easy to, Yi Xieli It measures lesser doctor or even is unable to complete the firing action of stapler, in order to complete to fire, doctor usually needs extremely to exert oneself, hand Therefore the stability of art cannot be guaranteed.

Utility model content

The utility model aim is to design a kind of nail kit component that can reduce percussion force, to reduce operating difficulty, improves hand Art stability.

The utility model solves technical problem and adopts the following technical scheme that a kind of nail kit component that can reduce percussion force, packet The nail kit pedestal for including I-shaped push broach bar and push broach bar being allowed to pass through, wherein be provided with rolling member on the nail kit pedestal.

Preferably, it is provided with the groove that can accommodate the rolling member on the nail kit pedestal, the rolling member is embedded in institute It states in groove, and is rotatably coupled with the nail kit pedestal.

Preferably, the exposed profile in the groove exterior portion of the rolling member protrudes from the nail kit pedestal appearance Face, or it is concordant with the nail kit base outer surface.

Preferably, the bracket that can support the rolling member, the rolling member and the branch are provided on the nail kit pedestal Frame is rotatably coupled.

Preferably, the rolling member includes cylindrical, spherical.

The utility model has the following beneficial effects: reducing required percussion force in stapler operation, it is difficult to reduce operation Degree improves stapler operational stability.

Fig. 4 is the utility model schematic structural diagram of the second embodiment；

1. push broach bar in figure, 2. nail kit pedestals, 3. rolling members.

Specific embodiment

The technical solution of the utility model is further elaborated below with reference to examples and drawings.

Embodiment one

As shown in Figure 1-3, present embodiments providing a kind of nail kit component that can reduce percussion force, including I-shaped push broach bar The 1 nail kit pedestal 2 passed through with permission push broach bar, wherein be provided with rolling member 3 on the nail kit pedestal.

Preferably, at the changed position in 2 surface of nail kit pedestal, respectively it is arranged one in 1 sliding channel two sides of push broach bar A groove, the groove can inlay rolling member 3, so that rolling member 3 is rotatably coupled with the nail kit pedestal 2 and are unlikely to Fall off, and the exposed profile in the groove exterior portion of rolling member 3 protrudes from 2 outer surface of nail kit pedestal, or with it is described 2 flush with outer surface of nail kit pedestal.The structure of the rolling member 3 is the cylinder that both ends diameter is greater than mid diameter, i.e. dumb-bell shape.

When carrying out anastomosis operation, doctor adjusts nail kit module position according to lesion situation, holds firing handle or percussion Bar makes I-shaped push broach bar 1 advance to distal end, since push broach bar 1 is contacted with rolling member 3, increases by nail kit susceptor surface Region when, the resistance that is subject to is the rolling friction from rolling member 3.Therefore it is directly contacted with nail kit pedestal 2 compared to push broach bar 1 Structure, technical solutions of the utility model rolling friction greatly reduces needed for percussion stapler instead of sliding friction Strength.

Embodiment two

As shown in figure 4, being passed through during the changed position in 2 surface of nail kit pedestal and push broach bar are advanced to distal end Position at the multipair rolling member 3 of setting.Rest part is the same as example 1.

Embodiment three

The bracket that can support the rolling member is provided on the nail kit pedestal, the rolling member and the bracket can be rotated Ground connection.Other are the same as example 1.

Example IV

The rolling member 3 is spherical shape, remaining is the same as example 1.

Finally, it should be noted that above embodiments are only to illustrate the technical solution of the utility model, rather than its limitations； Although the utility model is described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: It is still possible to modify the technical solutions described in the foregoing embodiments, or part of technical characteristic is carried out etc. With replacement；And these are modified or replaceed, various embodiments of the utility model technology that it does not separate the essence of the corresponding technical solution The spirit and scope of scheme.
