Abstract
The invention provides an accessory for sleeving a puncturing rod. The accessory is an extension body with two ends; one end is a clamping part for clamping the puncturing rod; and the other end is a streamline smooth part. The accessory has the advantages that: if the puncturing rod of a surgical tubular binding instrument is sleeved with the accessory after puncturing is finished, the puncturing rod cannot puncture useful tissues and is safe and reliable.
Description
Technical field
The present invention relates to a kind of adnexa of tubular type binding instrument of surgical operation use, belong to medical apparatus and instruments
Technical field.
Background technology
Surgery is a kind of medical apparatus and instruments that often uses when physiological tissues such as intestinal are carried out surgical operation with the tubular type binding instrument, and the difference of this instrument performance plays crucial effects for the whole surgery effect.Bookbinding form in this class Binding Instrument mostly adopts is axially organized containingly for two sections during bookbinding, forms binder ring at organization internal, and U.S. Pat 5205459 has promptly disclosed a kind of tubular type binding instrument with said structure.The advantage of this apparatus is: the body that produces in the operation process is hemorrhage can be along with content be discharged together, and operation back body tissue ratio is easier to healing.
In some surgical operations that use this apparatus, the puncturing lever of need on pin anvil shaft, pegging graft, and because the head of puncturing lever is sharp bore spine shape, so puncturing lever is easy to stab the useful tissue of periphery after puncture is finished.
The present invention quotes the content that this patent is put down in writing as prior art.
Summary of the invention
The objective of the invention is to solve above-mentioned technical problem, a kind of adnexa that is socketed on puncturing lever is provided, guarantee the tissue that puncturing lever can not damage when passing tissue.
Purpose of the present invention is achieved through the following technical solutions:
A kind of adnexa that is used for sleeving puncturing rod is one to have the ennation at two ends, and an end is the clamping part that is used for the clamping puncturing lever, and the other end is the smooth department of streamlined setting.
Further, described clamping part is a flexure strip.The outline of described clamping part and puncturing lever is complementary.
Again further, described clamping part is provided with and the corresponding projection of the groove of puncturing lever.
Further, described smooth department is the vertex of a cone of an arc transition, and the described vertex of a cone is extended with the awl end to clamping part.Perhaps, described smooth department is a spheroid.
Beneficial effect of the present invention is mainly reflected in: when surgery puts above-mentioned adnexa with the puncturing lever of tubular type binding instrument after puncture is finished, just can not stab useful tissue, and safe and reliable.
Description of drawings
Below in conjunction with accompanying drawing technical solution of the present invention is described further:
Fig. 1: first embodiment of the invention is socketed on the sketch map behind the puncturing lever.
Fig. 2: the sketch map of first embodiment of the invention.
Fig. 3: second embodiment of the invention is socketed on the sketch map behind the puncturing lever.
Wherein:
1 pin anvil shaft, 2 puncturing levers, 3 clamping parts
4 vertex of a cones, the 5 awl ends 6 spheroids
7 projections, 8 grooves
The specific embodiment
The present invention has disclosed a kind of adnexa of tubular type binding instrument.
The same with prior art, comprise the nail anvil and the pin anvil shaft 1 that are arranged on the Binding Instrument front end, puncturing lever 2 is removably disposed on the pin anvil shaft 1, and puncturing lever 2 also can be fixedly installed on the top anvil axle 1 certainly.Because puncturing lever 2 needs to wear out tissue in operation, so its head generally all is sharp-pointed shape.Wear out the tissue that tissue back puncturing lever 2 is stabbed health in order not allow, so the present invention is at adnexa of front end socket of puncturing lever 2.This adnexa is one to have the ennation at two ends, and an end is the clamping part 3 that is used for clamping puncturing lever 2, is complementary with the outline of puncturing lever 2; The other end is the smooth department 4,6 of streamlined setting.
As depicted in figs. 1 and 2, in the first embodiment of the present invention, described clamping part 3 is a flexure strip.Described clamping part 3 is provided with the groove 8 corresponding projections 7 with puncturing lever 2.After the sharp-pointed head of puncturing lever 2 extend in the clamping part 3, projection 7 cooperates with groove 8 was clamped on the puncturing lever 2 adnexa.Described smooth department is the vertex of a cone 4 of an arc transition, and this vertex of a cone 4 is extended with the awl end 5 to clamping part 3.The reason that the awl end 5 is set is for protective tissue further, prevents that the intersection of clamping part 3 and puncturing lever 2 from pulling tissue.
As shown in Figure 3, the smooth department of present embodiment is a spheroid 6, is similarly slick front end.Flexure strip as clamping part 3 is also short slightly, as long as can entangle the sharp-pointed portion of clamping part 3.
Because useful tissue can not taken and pull to the setting of the circular arc vertex of a cone 4 and spheroid 6 therefore to when the tubular type binding instrument passes tissue.The present invention still has multiple concrete embodiment, for example setting of smooth department, and the surface that only needs streamlined or circular arc gets final product, and is not limited to circular cone top or spheroid.All employings are equal to replacement or equivalent transformation and all technical schemes of forming, all drop within the scope of protection of present invention.
