Abstract
The invention discloses a tubular thread cutting and removing device, which comprises an outer sleeve and a cutter bar, wherein the front end of the outer sleeve is in arc-shaped beveling, an arc-shaped opening groove which is convenient for a suture to enter is cut in the outer bottom wall of the outer sleeve, the edge of the front side of the opening groove is edged, and the front end of the cutter bar is in arc-shaped beveling and edged at the end head; when the cutter bar is pushed forwards, the front end of the cutter bar is pushed through the open slot, but does not exceed the outer convex bottom surface pipe wall; the advantages are that: 1. shearing the suture in the mouth by utilizing the shearing force formed by the cutting edge at the front end of the cutter bar and the cutting edge at the side edge of the open slot; the in-situ thread cutting can not drag the soft tissues of the human body and can not increase pain; 2. the little finger can push the pushing rod to perform thread cutting operation.
Description
Technical Field
The invention relates to an appliance for shearing off suture of a suture soft tissue after a complex resist tooth plucking operation, in particular to a tubular suture shearing and dismantling device.
Background
The wound is usually sutured with sutures after tooth extraction or other oral surgery for better healing; at present, ophthalmic scissors or thread scissors are mainly used in clinic to trim thread ends after suturing or suture after healing, but the oral cavity is narrow in space, unclear in visual field and deep in suture position; the front end of the ophthalmic scissors or the wire scissors is also provided with a cutting edge, so that the soft tissues or other tissues of the mucous membrane can be sheared when the operation is not good, and unnecessary damage and pain are brought to a patient.
Disclosure of Invention
Aiming at the defects of the prior art, the invention provides a tubular thread cutting and removing device which can not cut soft tissues or other normal tissues of mucous membranes.
In order to solve the technical problems, the invention is solved by the following technical scheme: the tubular thread cutting and removing device is characterized in that: the outer sleeve comprises an outer sleeve and a cutter bar, wherein the front end of the outer sleeve is in arc-shaped beveling, an arc-shaped opening groove which is convenient for a suture to enter is cut in the outer convex bottom surface pipe wall, the edge of the front side of the opening groove is edged, and the front end of the cutter bar is in arc-shaped beveling and edged at the end; when pushing forwards, the front end of the cutter bar pushes through the open slot, but does not exceed the outer convex bottom surface pipe wall.
The middle position of the cutter bar is turned inwards to form a slender waist bar, two semicircular petals and a spring are sleeved outside the slender waist bar, the semicircular petals are fixed on the outer sleeve through screws, and the spring is clamped between the semicircular petals and the step surface of the slender waist bar.
The middle rear part of the cutter bar is provided with a pushing rod which is convenient for the manipulation of the little female finger, the tail end of the outer sleeve is provided with a rod groove which is arranged on the wall of the bottom surface pipe, and the pushing rod is movable in the rod groove
Compared with the prior art, the invention has the following beneficial effects: 1. shearing the suture in the mouth by utilizing the shearing force formed by the cutting edge at the front end of the cutter bar and the cutting edge at the side edge of the open slot; the in-situ thread cutting can not be pulled to soft tissues and pain can not be increased; 2. the little finger can push the pushing rod to perform thread cutting operation.

Fig. 2 is a schematic front view of the pop-up operation according to the embodiment of the present invention.
FIG. 3 is a schematic top view of an embodiment of the present invention in shear.
Fig. 4 is a schematic diagram illustrating the front view of the embodiment of the present invention in cutting.
Fig. 5 is an exploded view of the structure of an embodiment of the present invention.
Detailed Description
The invention is described in further detail below with reference to the attached drawings and detailed description: see fig. 1-5; the figures are marked as follows: the outer sleeve 1, the cutter bar 2, the open slot 3, the slender waist bar 4, the semicircular valve 5, the spring 6, the screw 7, the push rod 8 and the bar slot 9.
The tubular thread cutting and removing device comprises an outer sleeve 1 and a cutter bar 2, wherein the front end of the outer sleeve is in arc-shaped beveling, an arc-shaped opening groove 3 which is convenient for a suture to enter is cut in the outer convex bottom surface pipe wall, the edge of the front side of the opening groove is edged, and the front end of the cutter bar is in arc-shaped beveling and edged at the end; when pushing forwards, the front end of the cutter bar pushes through the open slot, but does not exceed the outer convex bottom wall.
The middle position of the cutter bar is turned inwards to form a slender waist bar 4, two semicircular petals 5 and a spring 6 are sleeved outside the slender waist bar, the semicircular petals are fixed on the outer sleeve through screws 7, and the spring is clamped between the semicircular petals and the step surface of the slender waist bar, so that the cutter bar can rebound and reset due to the design.
The middle rear part of the cutter bar is provided with a pushing rod 8 which is convenient for the manipulation of the little finger, the tail end of the outer sleeve is provided with a rod groove 9 which is arranged on the wall of the bottom surface, and the pushing rod moves in the rod groove; the structure of the chain and the snare can be also arranged, or other modes which are beneficial to the hooking and the movement of the little finger; when the outer sleeve is operated by one hand, the four fingers hold the outer sleeve stably enough, the little finger can be released to push the push rod, and the little finger of a normal person can push 6-8 mm forwards when being opened, and the little finger is 3-5 mm too; but the suture does not cross 0.5 mm, the distance is sufficient, and the pushing force provided by the little finger is also sufficient to sever the suture.
