The following examples are carried out on the premise of the technical solution of the present invention, and detailed embodiments and specific operation procedures are given, but the scope of the present invention is not limited to the following examples.

Example 1

A titanium clamp apparatus for facilitating adjustment of a titanium clamp, comprising: the clamp comprises a clamp component 1, a fixed seat 3, a control handle 4, a sheath tube 5, a clamping arm 11, a closed part 12, a semicircular body 13, a boss structure 14, a fixed groove 15, a nylon wire 21, a wire drawing fracture part 22, a wire drawing 23, a knife groove 24, a limiting body 25, a nylon wire fixing part 26, a nylon wire groove 27, a 28-thick wire drawing, a nylon wire hole 29, a long hole structure 31, a first elastic sheet 32, a first blocking sheet 33, a blade 41, a finger ring 42, a sheath tube connecting part 51, a hose 52, a second elastic sheet 53 and a second blocking sheet 54.

As shown in fig. 1 to 5, the clip assembly 1 of the present embodiment is a component that is nested in the fixing seat 3. As shown in fig. 6, the clip assembly 1 comprises a rectangular boss structure 14 and a fixing slot 15, at least two clipping arms 11 and a closing portion 12 which can be deformed to close the clipping arms 11, and a semi-circular body 13 which can be deformed to open and close the clipping arms, so as to tighten the target tissue, for example, to tighten the wound to stop bleeding. The holder is attached at its proximal end with a pull 23 and a nylon wire 21, with a pull break 22 at the junction of the pull 23 and the clip assembly 1.

As shown in fig. 7, the fixing seat 3 located at the proximal end of the clip assembly 1 has a rectangular long hole structure 31 matching with the rectangular boss structure 14 on the clip assembly 1, a first resilient tab 32 bent toward the axis matching with the fixing groove 15 on the clip assembly 1, and a first stop tab 33 axially limiting with the clip assembly 1 and the second stop tab 54 on the sheath 5. Wherein the clip assembly 1 and the holder 3 are made of a biocompatible material.

In the initial state, that is, when the titanium clip is not closed and released, as shown in fig. 3 to 5, the clip arms 11 and the closing portion 12 are in the open state due to the elasticity, and the rectangular boss structures 14 on the clip assembly 1 are in embedded fit with the rectangular long hole structures 31 on the fixing base 3, so that the clip assembly 1 can perform a certain range of movement in the axial direction.

As shown in fig. 7 and 8, in order to provide the added nylon yarn 21 with enough space in the tube, the first blocking piece 33 and the second blocking piece 54 are preferably semicircular ring-shaped blocking pieces.

As shown in fig. 8 and 11, the sheath 5 is composed of a hard tube on the distal end side and a soft tube 52 on the proximal end side. The rigid tube has a second elastic sheet 53 which is matched with the rectangular long hole structure 31 on the fixed seat 3 and is bent towards the axis, and a semicircular second baffle 54 which is used for carrying out axial limit with the first baffle 33 on the fixed seat 3. Wherein the hose 52 may take the coiled configuration of the present embodiment or, alternatively, any other suitable hollow, flexible configuration.

In the initial state, that is, when the titanium clip is not closed and released, as shown in fig. 4 and 8, the sheath 5 is buckled with the rectangular long hole structure 31 on the fixing base 3 through the second elastic sheet 53 thereon and connected with the fixing base 3, and simultaneously the first blocking sheet 33 on the fixing base 3 is attached to the second blocking sheet 54 in the sheath, so as to realize axial and radial fixation of the sheath 5 and the fixing base 3.

Because the clamp assembly 1 and the fixed seat 3 are matched through the rectangular boss structure 14 and the rectangular long hole structure 31, the clamp assembly and the fixed seat can be limited in the circumferential direction, namely when the clamp assembly 1 rotates in the circumferential direction, the clamp assembly can drive the fixed seat 3 to rotate in the circumferential direction; similarly, because fixing base 3 and sheath pipe 5 pass through rectangle slot hole structure 31 and the cooperation of second shell fragment 53, both have spacing ascending in week, so when 3 circumferential direction of fixing base, can drive 5 circumferential direction of sheath pipe. As shown in fig. 8 and 11, in order to avoid the influence of a large torque included in the circumferential rotation of the entire sheath 5 on the normal circumferential rotation of the distal clip assembly 1, the sheath 5 is divided into a distal hard tube and a proximal soft tube 52 that can rotate freely circumferentially with respect to each other, and the two are connected to each other through a sheath connection portion 51 so as to rotate freely circumferentially and to generate axial and radial position limitation. At this time, the circumferential rotation of the above clip assembly 1 and the fixing seat 3 does not drive the hose 52 to rotate circumferentially.

As shown in fig. 1, 12 and 13, the proximal end of the titanium forceps of the present invention is a control handle 4, the distal end of the control handle 4 is connected to a sheath hose 52, a thick wire 28 with a nylon wire groove 27 and a nylon wire hole 29 is inserted therein, and the proximal end has a blade 41 capable of cutting off the radial nylon wire fixing portion 26 through the knife groove 24. The thick wire 28 is attached to the inner wall of the sheath tube 5, coaxial radial limiting of the thick wire 28 and the sheath tube is achieved, the far end of the thick wire 28 is connected with the wire drawing 23, and the nylon wire 21 is communicated with the nylon wire groove 27. As shown in fig. 13, the finger ring 42 capable of being pulled by fingers is connected to the proximal end side of the rough wire 28, the connection mode can adopt various connection modes which can enable the rough wire 28 and the finger ring 42 to synchronously move axially, the rough wire 28 extends to a distance from the proximal end side of the finger ring 42, and the limiting body 25 with the knife groove 24 and capable of being matched with the control handle 4 is connected to the proximal end edge of the rough wire 28. Wherein, the finger ring 42 can move axially along the control handle 4 within a certain range, and the axial movement can drive the rough drawing wire 28 to move axially. As shown in fig. 13, 15 and 17, a nylon wire 21 is wound on a section of the rough drawn wire 28 between the stopper body 25 and the finger ring 42, the nylon wire 21 is wound through a nylon wire hole 29 perpendicular to the axial direction on the rough drawn wire 28 to form a nylon wire fixing portion 26, and the knife groove 24 extends from the stopper body 25 to a distance above the rough drawn wire 28 on the distal end side of the nylon wire fixing portion 26. As shown in fig. 16 and 14, the nylon wire fixing portion 26 is wound such that the nylon wire 21 has a radial line segment, so that the nylon wire 21 can be cut by the blade 41 when the stopper body 25 and the thick drawn wire 28 are axially moved proximally.

As shown in fig. 14, the above-mentioned spacing body 25 and the control handle 4 are matched to have a circumferential spacing, and the coarse drawing wire 28 and the drawing wire 23 can be driven to circumferentially rotate by operating the control handle 4 to circumferentially rotate by hand, so that the clamp assembly 1 can realize controllable circumferential rotation according to the above-mentioned structure.

After the embodiment is delivered to the vicinity of the target tissue through a professional medical endoscope, according to the structure, the titanium clip can be controlled to reach the target position and be adjusted to the target angle through the control handle 4, and at the moment, the finger ring 42 is pulled towards the proximal end to drive the rough drawing wire 28 until a series of components of the clip component 1 move towards the proximal end in an axial direction. As shown in fig. 9 and 10, when the clip assembly 1 moves axially towards the proximal end relative to the fixed seat 3, according to the structural characteristics of the clip assembly 1, the closing portion 12 of the clip assembly 1 enters the tube of the fixed seat 3, and due to the action of the radial force, the closing portion 12 deforms, so that the clipping arms 11 close and clip the tissue. After a resistance force, the near-end surface of the clamp assembly 1 is attached to the blocking piece 33 on the fixed seat, and at the moment, the fixed groove 15 is buckled with the first elastic sheet 32 after passing through the first elastic sheet 32, so that the fixation of the clamp assembly 1 and the fixed seat 3 and the closed locking of the clamping arm 11 are realized; meanwhile, the rectangular boss structure 14 moves to the second elastic sheet 53 along the rectangular long hole structure 31, and applies a radially outward force to the second elastic sheet 53 to make the second elastic sheet 53 radially outward bend, so that the second elastic sheet 53 opens and is disengaged from the rectangular long hole structure 31, thereby realizing the separation of the fixed seat 3 and the sheath tube 5. The ring 42 is continuously pulled axially towards the proximal end to overcome the resistance, so that the wire breaking part 22 is broken, the wire 23 is separated from the clamp assembly 1, and the clamp assembly 1 and the fixed seat 3 are released. Since nylon filament 21 is slightly longer than pull filament 23, it will not be pulled apart and will remain distally attached to clip assembly 1. As shown in fig. 14, when the finger ring is pulled proximally along the axial direction 42 to the most proximal end, i.e. when the proximal end surface of the stopper body 25 is in surface contact with the control handle 4, the wire-pulling fixing part 26 and the blade 41 move axially toward each other in the process, and the blade 41 enters the knife groove 24 to cut off the radial part of the nylon wire connecting part 26, so that the nylon wire 21 is separated from the titanium clip device of the present embodiment at the proximal end. The titanium clip is withdrawn from the body and the nylon wire 21 connecting clip assembly 1 is extended outside the body. The angle adjustment of the in-vivo detaining component can be realized by pulling the nylon wire 21 exposed outside the body, for example, when a large wound is sutured by a nylon rope, the nylon wire 21 exposed outside the body can be pulled to keep the ideal state that the in-vivo detaining component is vertically upright with the nylon rope surface. After the adjustment is completed, the nylon wire 21 can be cut off at the distal end by an electric knife, and the nylon wire 21 can be taken out.

It should be noted that the present embodiment is only one of the exemplary embodiments, and is only used for illustrating the technical solution of the present invention, and not for limiting the same. Although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those skilled in the art; it is also possible to modify the solutions described in the above embodiments or to substitute some or all of the technical features of them equally. Such modifications and substitutions do not depart from the spirit and scope of the present invention.

For example, the clip assembly 1 used in the above embodiments is closed by the closing portion 12 being pressed radially by the fixing base 3 during the axial movement, and a clip assembly using a transmission rod or other principle as a closing means may be used instead; in the above embodiment, the design of the double-ear finger ring 42 is adopted, and the design of the cylindrical pull ring can also be adopted; in the above embodiments, the first elastic sheet 32 and the long hole structure 31 are designed as a pair, or two or more pairs may be adopted as required.
