Description

Split type soft tissue clamp capable of being repeatedly closed and repeatedly used under endoscope

Technical Field

The utility model belongs to the field of medical instruments, in particular to a split type soft tissue clamp which can be repeatedly closed and repeatedly used under an endoscope.

Background

Conventional soft tissue clips known as japanese patent application laid-open nos. 2002-191609 and 2004-121485 have the following problems.

When the soft tissue clamp is used for positioning a soft tissue target area, the elastic clamping wings of the sleeve of the clamp component are clamped with the end surface of the front end part of the flexible component, so that the sleeve is prevented from being immersed into the flexible component. The clamp has been oriented to position the jaws of the clamp so that the target area is enclosed within the jaws. Then, while pressing the base end of the flexible assembly, the push-pull ring of the operation part is pulled back, so that the elastic claw arm of the clip is pulled into the tube of the sleeve. At the moment, the front end wall of the cylinder channel can apply force to the elastic claw arms along the direction of the central shaft of the cylinder channel from the contact points, so that the elastic claw arms and the claws are clamped towards the center of the soft tissue area. And the push-pull ring of the operating part is continuously pulled back, and at the moment, the target soft tissue generates pulling resistance and the soft tissue area also gives counterforce to the elastic claw arms and gradually increases along with the clamping of the elastic claw arms to the center of the soft tissue target area. When the wound is large, the larger the area to be clamped, the clip often fails to clamp the tissue and the elastic claw arm deforms.

The push-pull ring of the operation part is continuously pulled back, the pull rod is under the action of the tension force in the two directions along the central shaft at the moment, the base ends of the claw arms of the clamps are clamped at the clamping grooves, the pulling force of the tissues is directly applied to the clamping grooves, the deviation force is generated, the front end of the pull rod is bent in the opposite direction of the opening of the clamping grooves due to the force, and the top point of the front end of the pull rod is abutted to the position, in the sleeve channel, of the elastic clamping wing of the sleeve. The pulling force continues to increase, with a consequent increase in the biasing force that has caused the resilient catches to open excessively, the structure of which prevents the resilient jaw arms of the clip from continuing to pull into the sleeve, the jaws of the clip being unable to sufficiently grip the soft tissue target area.

In conclusion, the conventional soft tissue clamp has the defects in the use process, the clamp cannot be opened again once being closed, other instruments are required to be replaced to pull out the clamp when the clamp assembly is released wrongly after being closed, the gastrointestinal mucosa wall at the closed part is easily pulled and even the gastrointestinal tract is perforated, and thus clinical medical accidents are caused.

However, all soft tissue clamps used in clinic, which can realize repeated opening and closing, are single-use integrated type, that is, the pushing system and the clamp assembly are pre-assembled together before use, and once the clamp assembly and the pushing system are closed, the pushing system and the clamp assembly cannot be assembled for use again after use, such as the soft tissue clamps with the application numbers of: 201220250652.7 hemostatic clip with pusher capable of being opened and closed repeatedly. Because the product is disposable and can realize the repeated closing function, the structure is complex, the price is very high, and great economic burden is brought to clinical patients when the product is used.

Referring to fig. 9, when the clip 5 on the clip assembly 1 needs to be opened again to close the mucosal tissue 9 again, the pull ring 7a is pushed, the waisted shaft 4e at the front end of the pull rod member 4 is located below the snap wings 3c of the sleeve 3, so that the snap wings 3c cannot deform further in the radial direction of the sleeve 3, the snap wings 3c contact with the stepped shaft structure 6a-1 on the top end 6a of the flexible assembly 6 when the pull ring 7a is pushed further, the sleeve 3 is prevented from moving forward by the stepped shaft structure 6a-1 on the top end 6a of the flexible assembly 6, after the sleeve 3 is limited by the stepped shaft structure 6a-1 on the top end 6a of the flexible assembly 6, the pull ring 7a is pushed further, and the metal claw 5 protrudes from the inside of the sleeve 3, thereby realizing the re-opening of the clip.

Example 1:

a split type soft tissue clamp which can be repeatedly closed and reused under an endoscope. The soft tissue clip comprises a clip assembly 1 and a pusher system 2. The pushing system 2 comprises a flexible component 6 and an operation part 7; the clip assembly 1 comprises a sleeve 3, a pull rod member 4 and a clip 5.

The flexible member 6 includes a distal end portion 6a, a proximal end portion 6c, and a flexible tube 6b between the distal end portion 6a and the proximal end portion, and the distal end portion 6a is inserted forward into a jaw of an endoscope inserted into a body cavity.

As shown in fig. 6-7, the upper portion of fig. 7 is an enlarged view of the circled portion on the right side of fig. 6. The operating portion 7 is movable within the flexible member 6, and the tapered head 7b is connected to the clip member 1, and the tapered head 7b thereof enters and exits at the tip end portion 6a of the flexible member 6. A push-pull ring 7a is provided at the proximal end of the operation section 7, and by operating the push-pull ring 7a, the tapered head 7b can be moved in and out of the distal end portion 6a of the flexible unit 6, whereby the movement of the clip unit 1 connected thereto into and out of the distal end portion 6a of the flexible unit 6 is controlled, and the opening and closing of the clip 5 of the clip unit 1 is controlled. Preferably, the flexure 6 is provided with a through hole along its axial direction to connect the end of the operating portion 7 with the outer push-pull ring 7 a.

The outer diameter of the sleeve 3 is smaller than the inner diameter of the opening of the tip portion 6a of the flexible member 6, so that the clip member 5 can be advanced and retracted along the center line of the cylindrical passage 3a, the cylindrical passage 3a being a circular sleeve passage. At the same time, the plurality of elastic claw arms 5a of the clip 5 are elastically opened and closed during the process of advancing and retracting the cylinder path 3a thereof. The sleeve 3 is provided with an elastic clip wing I3b and an elastic clip wing II3c corresponding to the elastic clip wing I3b on the periphery, and the elastic clip wing can be elastically opened and closed along the radial direction of the sleeve 3. As shown in FIG. 5, during the operation of operating portion 7 to pull clip assembly 1 into distal end portion 6a of flexible member 6, resilient snap wings I3b and resilient snap wings II3c contact a trapezoidal shaped groove 8a on clip assembly package 8, and resilient snap wings I3b and resilient snap wings II3c are forced to contract radially inwardly of sleeve 3 until resilient snap wings I3b and resilient snap wings II3c enter flexible member 6 and are urged by their inner peripheral arms to prevent opening. The proximal end 5b of the claw arm has a convex point structure, and when the clip assembly 1 is pulled into the flexible assembly 6 by the tapered head 7b of the operating portion 7, the convex points prevent the sleeve 3 from moving relative to the pull rod member 4, so that the elastic clamping wings 3b of the sleeve 3 are ensured to be bent and deformed in the radial direction thereof, and finally, the clip assembly 1 is ensured to enter the flexible assembly 6.

When the operating portion 7 pushes the clip unit 1 out of the distal end portion 6a of the flexible unit 6, the elastic snap wings I3b elastically open immediately after being pushed out of the distal end portion 6a of the flexible unit 6, and engage with the pipe arm end face of the distal end portion 6a of the flexible unit 6 in a direction along the longitudinal center line of the flexible unit 6.

The pull rod member 4 is arranged in the barrel path 3a of the sleeve 3 and can freely move along the extension direction of the barrel path 3a, the tail end U-shaped part of the clamp 5 is clamped in the clamping groove 4c of the front end 4b of the pull rod, the front end of the pull rod member 4 is provided with a waist-round shaft 4e, the middle of the pull rod member is provided with a pull rod shaft 4f, and the pull rod shaft 4f is an oval shaft or a round shaft. The tapered head 7b of the operating portion 7 is connected to the inside of the rod proximal end hole 4d, and is moved along the cylindrical passage 3a of the sleeve 3 together with the clip 5 by being operated by the proximal end push-pull ring 7a of the operating portion 7. The pull rod member 4 has a breaking portion 4a which breaks when the operating portion 7 applies a tensile load equal to or greater than a predetermined value after the elastic snap wings 3b of the sleeve 3 engage with the end faces of the distal end portion 6a of the flexible unit 6.

The clip 5 is provided with a plurality of elastic claw arms 5a which can grasp and clamp soft tissues in the alimentary canal, when the fracture part 4a of the pull rod component 4 is fractured, the clip 5 moves into the barrel channel 3a of the sleeve 3 under the action of tensile force to close the opened claws 5c, and the

grooves

5d and 5e of the two claw arms on the middle two arms of the clip 5 are clamped into the stepped hole 3g at the front end of the sleeve 3 after closing.

The tail end of the sleeve 3 is provided with a waist-shaped stepped shaft hole 3d, and a final fracture part 3f is designed between the elastic clamping wing I3b and the elastic clamping wing II3c of the sleeve 3. When the clip assembly pre-closes the mucosal tissue 9, the conical head 7b of the operating part 7 is connected in the pull rod base end hole 4d, the pull ring 7a is pushed by the base end of the operating part 7 to move along the barrel channel 3a of the sleeve 3 together with the clip 5 until the end surface 4e-1 of the waist-shaped shaft 4e arranged at the front end of the pull rod member 4 is contacted with the inner end surface 3e of the waist-shaped stepped shaft hole 3d arranged at the tail end of the sleeve 3, and the waist-shaped shaft 4e at the front end of the pull rod member 4 is positioned below the elastic clamping wing II3c on the sleeve 3, at the moment, the pulling of the operating part to push the pull ring 7a is stopped.

When the clamp 5 on the clamp assembly 1 needs to be opened again, the pull ring 7a is pushed, the snap wings 3c cannot be deformed in the axial direction of the sleeve 3 continuously because the waisted shaft 4e at the front end of the pull rod member 4 is positioned below the snap wings 3c on the sleeve 3, the snap wings 3c contact with the stepped shaft structure 6a-1 on the top end part 6a of the flexible assembly 6 when the pull ring 7a is pushed continuously, and the sleeve 3 stops moving, so that the re-opening and closing of the clamp are realized.

As shown in fig. 11a-11 d. When the target tissue is closed again and the finally clamped tissue is determined to be free of problems, the end face 4e-1 of the oval shaft 4e at the front end of the pull rod member 4 of the pull ring 7a is continuously pulled to be in contact with the inner end face 3e of the oval-shaped stepped shaft hole 3d arranged at the tail end of the sleeve 3, the force applied to the pull rod member 4 by the pull ring 7a is transmitted to the sleeve 3, the sleeve final breaking part 3f is broken firstly after the sleeve 3 is pulled by 10-20N, and at the moment, the two

claw arm grooves

5d and 5e on the two middle arms of the clamp 5 of the pull ring 7a are continuously pulled to be clamped into the stepped hole 3g at the front end of the sleeve 3. At which point the clip 5 stops moving relative to the sleeve 3. When the pull ring 7a is pulled continuously, the front end fracture part 4a of the pull rod member 4 is stressed, when the pulling force reaches 30-50N, the front end fracture part 4a of the pull rod member 4 is fractured, finally, the clip assembly 2 is separated from the pushing system 1, the head of the clip assembly 1 is left in the body after closing the tissue, and the pushing system 1 can be pulled out from the endoscope instrument channel after finishing the closing action of the clip assembly 1. At this time, the pull ring 7a is pushed, the pull rod member moves towards the top end of the flexible assembly 6, the top surface of the flexible assembly 6, which is extended out by the waisted shaft 4e at the front end of the pull rod member 4, continues to push the pull rod member 4, the convex hull 4g at the tail end of the pull rod shaft 4f on the pull rod member 4 contacts with the tail end surface of the stepped hole 3g at the front end of the sleeve 3, at this time, because phi 2 is less than phi 1, the clamping wings 3c of the sleeve 3 deform axially, so that the sleeve 3 and the pull rod member 4 after being broken are finally removed from the flexible assembly 6, and the pull rod member 4 is pulled by hand to deflect, so that the sleeve 3 and the pull rod member 4 after being broken can be removed from the conical head 7b of the pushing system 2. In this way, the pushing system 2 can be reused again, and the above steps can be repeated to continue to connect the clip assembly 1 to close the soft tissue in the alimentary tract.
