Description

Technical Field

[0001] The present invention relates to a separate closure clip and a separate continuous-firing closure clip structure composed of the same, and more particularly to a separate closure clip having a jaw assembly that is a pivoting mechanism and is composed of two rigid clips pivotally connected, and each separate closure clip is controlled by an independent control line. The control line can be twisted and twisted into a multi-core stranded wire, and the connection portion of each control line is bent back on the multi-core stranded wire by different distances, thereby achieving the purpose of continuous firing of the separate closure clip. Background Art

[0002] Closure clips are commonly used in minimally invasive endoscopic surgery for wound closure and hemostasis. The principle is to close the wound surface with the clamping blade. However, wound dehiscence is usually closed with more than one clip. Therefore, single-shot clips require the magazine to be removed and reloaded during operation, which is inconvenient and increases surgical time.

[0003] Continuous closure clips include Chinese Patent No. CN108784775A "Multi-continuous tissue clip", Chinese Patent No. CN111568494A "A continuously releasable clamping device and operation method", Chinese Patent No. CN110613495A "A medical hemostatic clip", and Chinese Patent No. CN107106181A "Continuous ligation device".

[0004] In Chinese Patent No. CN108784775A, multiple closing clips are serially connected in a magazine. The clamp base of the closing clips is provided with an elastically deformable cross slot and a single operating lever (operating wire) is provided. The operating lever (operating wire) has a pull rod ring and is engaged with the cross slot of the frontmost closing clip. When the frontmost closing clip is fired, the pull rod ring of the operating lever (operating wire) disengages from the cross slot of the fired closing clip and engages with the cross slot of the next closing clip.

[0005] In Chinese Patent No. CN111568494A, multiple elastic clips are serially connected in a magazine. A clamping mechanism drives the elastic clips to a locked position during continuous release. The elastic clips are locked and restrained by the locking mechanism. The clamping mechanism then moves downstream, transitioning from a closed state to an open state. The open state of the clamping mechanism separates from the elastic clips. After the clamping mechanism transitions from the open state to the closed state again, it can engage with the rear end of another elastic clip.

[0006] In Chinese Patent No. CN110613495A, multiple closing clips are serially connected in a magazine. Each closing clip has a release hole. A release assembly on a control line engages with the release hole of the frontmost closing clip. When the frontmost closing clip is fired, the release assembly of the control line disengages from the release hole of the fired closing clip and engages with the release hole of the next closing clip.

[0007] In Chinese Patent No. CN107106181A, multiple clips are serially connected in a magazine, and a pull line is connected to the above multiple clips. Each clip includes a pair of clips. The tail of the clip is provided with a carrier sheet that will deform or break under a predetermined pressure. The clip forms a hole through the carrier sheet. The pull line passes through the hole formed by the carrier sheet and the front end of the pull line is blocked by the carrier sheet. When the frontmost clip is fired, the carrier sheet is broken, causing the clip to detach from the pull line.

[0008] The aforementioned continuous closing clip has the following problems in use:

[0009] 1. The closure clips in the aforementioned cases all use elastic clips, so the elasticity of the material must be considered (usually nickel-titanium alloy, cobalt-chromium alloy, etc.), and the materials that can be used are relatively limited.

[0010] 2. The aforementioned continuous-firing closing clips all use a single control line to control the firing of the closing clips, and the closing clips are directly connected in series through the control line. When the front closing clip fires, if the control line (for example, the end of the control line) does not accurately enter the connection and breaking mechanism of the next closing clip, the next closing clip may not be fired.

[0011] 3. The breech block clips in the aforementioned cases are all assembled in the magazine and must be removed from the magazine for firing. Summary of the Invention

[0012] Therefore, an object of the present invention is to provide a detachable closure clip and a detachable continuous closure clip structure composed of a plurality of detachable closure clips connected in series.

[0013] To achieve the above object, the technical solution adopted by the present invention is:

[0014] A split closure clip, characterized by comprising:

[0015] An outer sleeve having a front end and a rear end, the outer sleeve being relatively hollow from the front end to the rear end to form a passage, the front end having two retaining walls extending inwardly, two elastic retaining portions being recessed into the passage and tapering from the front end to the rear end, the front end having a first latching member and the rear end having a second latching member;

[0016] a clamping jaw assembly assembled in the channel of the outer sleeve, the clamping jaw assembly comprising a connecting piece, two clamping pieces and a release rope piece, the two clamping pieces being pivotally connected to the connecting piece, and having a clamping portion and an operating portion at opposite ends of the two clamping pieces, respectively; the operating portions of the two clamping pieces being blocking pieces arranged toward the opposite outsides and inclined toward the front end; when the split closing clamp has not yet been fired, the operating portions of the two clamping pieces are located between the blocking wall at the front end and the elastic blocking portion; the clamping portions of the two clamping pieces are relatively closed and extend from the front end of the outer sleeve; one end of the release rope piece is fixed to the connecting piece, and the other end is fixed to the second latching piece of the outer sleeve;

[0017] A control line has a connecting portion at the end thereof, and the connecting portion is connected to the connecting piece of the clamping jaw assembly.

[0018] In the split closing clamp, the clip of the clamping jaw assembly is made of a rigid material.

[0019] The described split closing clamp, wherein the connecting member of the clamping jaw assembly includes two connecting plates and a connecting rod connected between the two connecting plates, the two clamping plates are pivotally connected to the two connecting plates, and the connecting portion of the release rope and the control line is connected to the connecting rod.

[0020] In the split closure clip, the first latching member is a latching hole, and the second latching member is a corresponding latching protrusion.

[0021] The described separate closing clamp, wherein, when the separate closing clamp has not been fired, the release rope is reserved with an extension section; when the separate closing clamp is fired, the two clips extend out of the outer sleeve until the operating parts of the two clips press against the two retaining walls, causing the two clips to pivot and open relative to each other, and the release rope is extended through the extension section. Thereafter, the control line is pulled back to cause the two clips to pivot and close again, and the operating parts of the two clips pass over the two elastic retaining parts, and the release rope is pulled back and pulls the second latch member to move toward the relative inner side, and the pulling force of the control line causes a reaction force to accumulate on the connecting part of the control line, causing the stress of the connecting part to concentrate and break from the connecting part, completing the firing.

[0022] A separate continuous-fire closing clip structure, characterized by comprising:

[0023] Multiple separate closing clips are connected in series, and each separate closing clip includes:

[0024] An outer sleeve having a front end and a rear end, the outer sleeve being relatively hollow from the front end to the rear end to form a passage, the front end having two retaining walls extending inwardly, two elastic retaining portions being recessed into the passage and tapering from the front end to the rear end, the front end having a first latching member and the rear end having a second latching member;

[0025] a clamping jaw assembly assembled in the channel of the outer sleeve, the clamping jaw assembly comprising a connecting piece, two clamping pieces and a release rope piece, the two clamping pieces being pivotally connected to the connecting piece, and having a clamping portion and an operating portion at opposite ends of the two clamping pieces, respectively; the operating portions of the two clamping pieces being blocking pieces arranged toward the opposite outsides and inclined toward the front end; when the split closing clamp has not yet been fired, the operating portions of the two clamping pieces are located between the blocking wall at the front end and the elastic blocking portion; the clamping portions of the two clamping pieces are relatively closed and extend from the front end of the outer sleeve; one end of the release rope piece is fixed to the connecting piece, and the other end is fixed to the second latching piece of the outer sleeve;

[0026] a control line, wherein an end of the control line has a connecting portion connected to the connecting piece of the clamping jaw assembly;

[0027] Separate closure clips connected in series are locked by a first locking member of one of the adjacent outer sleeves to a second locking member of another adjacent outer sleeve;

[0028] an operating hose into which the plurality of control wires of the plurality of detachable closure clamps extend;

[0029] An elastic hose is wrapped around the operating hose. An adapter ring is provided at one end of the elastic hose. A third latching member is provided on the adapter ring. Among the series-connected separate closing clamps, the second latching member of the outer sleeve of the last separate closing clamp is latched on the third latching member of the adapter ring.

[0030] The described separate continuous closing clip structure, wherein the plurality of control wires are twisted and twisted into a multi-core twisted wire, the multi-core twisted wire having a first end and a second end, the end of each control wire being bent back at different distances from the first end to the second end, and the end of each control wire forming a plurality of connection portions extending from near the first end to the second end at intervals.

[0031] In the separate continuous-fire closing clamp structure, the clip of the clamping jaw assembly is made of a rigid material.

[0032] The described detachable continuous closing clamp structure, wherein the connecting part of the clamping jaw assembly includes two connecting plates and a connecting rod connected between the two connecting plates, the two clamping plates are pivotally connected to the two connecting plates, and the connecting part of the release rope and the control line is connected to the connecting rod.

[0033] In the separate burst-type closing clip structure, the first latching member is a latching hole, and the second latching member is a corresponding latching protrusion.

[0034] The described separate continuous-firing closing clamp structure, wherein, when the separate closing clamp has not yet been fired, the release rope is reserved with an extension section; when the separate closing clamp is fired, the two clips extend out of the outer sleeve until the operating parts of the two clips press against the two retaining walls, causing the two clips to pivot and open relative to each other, and the release rope is extended through the extension section, and then the control line is pulled back to cause the two clips to pivot and close again, and the operating parts of the two clips to pass over the two elastic retaining parts, and the release rope is pulled back and pulls the second latching part toward the relative inward displacement and disengages from the first latching part, and the pulling force of the control line causes a reaction force to accumulate on the connecting part of the control line, causing the stress of the connecting part to concentrate and break from the connecting part, completing the firing.

[0035] The above technical features can achieve the following effects:

[0036] 1. The jaw assembly of the split closure clamp is a pivoting mechanism consisting of two rigid clips pivotally connected, and can be used with a wider range of materials without being restricted by the elasticity of the materials.

[0037] 2. Each separate closure clip of the split-type continuous closure clip structure has a control line, so a single separate closure clip can be controlled by each independent control line (i.e., one control line controls one separate closure clip), without having to consider the alignment of the single control line with the breaking mechanism of each closure clip.

[0038] 3. The multiple control wires of the multiple separate closing clamps are twisted and spliced ​​into a multi-core stranded wire to ensure that the rear-end operating hose can actually drive each separate closing clamp, and the connection portion of each control wire is bent back at different distances from the first end to the second end of the multi-core stranded wire. By retracting the multi-core stranded wire, the control wire of the fired separate closing clamp can be retracted without interfering with the adjacent separate closing clamps, thereby completing the continuous firing of the separate closing clamps.

[0039] 4. The release rope is provided with an extension section so that the length of the release rope can be extended through the extension section when the separate closing clamp is fired. When the control line is pulled backward, the release rope is driven to pull the second latching member toward the relative inner side and disengage from the first latching member, so that adjacent separate closing clamps can be separated from each other; and the pulling force of the control line causes the reaction force to accumulate at the connecting part of the control line, causing the stress of the connecting part to concentrate and break; thereby achieving the function of complete firing.

[0040] 5. The adjacent separate closure clips of the split-type burst-firing closure clip structure are connected and fixed in series by the first and second latching members of the outer casing. When firing, the latching state is released by the release rope. The separate closure clips do not need to be assembled in the magazine. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0060] In view of the above technical features, the main functions of the detachable closure clip and the detachable continuous closure clip structure composed of a plurality of detachable closure clips connected in series in the present invention will be clearly demonstrated in the following embodiments.

[0061] See Figure 1 and Figure 2 As shown, each split closure clip 10 includes an outer sleeve 1, a clamping jaw assembly 2 and a control wire 3. In the figure, a plurality of control wires 3 are twisted and twisted to form a multi-core stranded wire 3A. The multi-core stranded wire 3A can be conveniently connected in series with a plurality of split closure clips 10 as described later to form a split continuous closure clip structure 20 (such as Figure 6 、 Figure 7 shown).

[0062] See Figure 3 and Figure 4As shown, the outer sleeve 1 has a front end 11 and a rear end 12. The outer sleeve 1 is relatively hollow from the front end 11 to the rear end 12 to form a channel 13. The front end 11 has two retaining walls 14 extending toward the relative inner side. Two elastic retaining portions 15 are provided near the front end 11, which are recessed into the channel 13 and relatively inclined and gradually contracted from the front end 11 to the rear end 12. A first latching member 16 is provided at the front end 11, and a second latching member 17 is provided at the rear end 12. In this embodiment, the first latching member 16 is a latching hole, and the second latching member 17 is a corresponding latching protrusion. The clamping jaw assembly 2 is assembled in the channel 13 of the outer sleeve 1. The clamping jaw assembly 2 includes a connecting piece 21, two clips 22 and a release rope piece 23. The two clips 22 are pivotally connected to the connecting piece 21, and the two opposite ends of the two clips 22 are respectively a clamping portion 221 and an operating portion 222. The operating portion 222 of the two clips 22 is a blocking piece arranged toward the relatively outer side and inclined toward the front end 11. When the separate closed clamp 10 has not been fired, the operating portion 222 of the two clips 22 is located between the retaining wall 14 and the elastic blocking portion 15 of the front end 11, and the clamping portions 221 of the two clips 22 are relatively closed and extend from the front end 11 to the outer sleeve 1, and one end of the release rope piece 23 is fixed to the connecting piece 21, and the other end is fixed to the second latching piece 17 of the outer sleeve 1, and an extension section 231 is reserved on the release rope piece 23. The end of the control line 3 has a connecting portion 31 , and the control line 3 is connected to the connecting piece 21 of the clamping jaw assembly 2 through the connecting portion 31 .

[0063] See Figure 5 As shown, specifically, the connecting member 21 of the clamping jaw assembly 2 includes two connecting plates 211 and a connecting rod 212 connected between the two connecting plates 211, and the two clamping plates 22 are pivotally connected to the two connecting plates 211, and the connecting portion 31 of the release rope 23 and the control line 3 is connected to the connecting rod 212, so that the clamping jaw assembly 2 constitutes a pivot mechanism, whereby the clamping plate 22 is opened or closed in a pivoting manner, so that the clamping plate 22 can be made of rigid material, and there is no need to consider the elasticity of the material, and a wider range of materials can be used.

[0064] See Figure 6 and Figure 7As shown, a plurality of separate closure clamps 10 are connected in series to form a separate continuous-firing closure clamp structure 20. The separate continuous-firing closure clamp structure 20 also includes an operating hose 4, an operating member, and an elastic hose 5. The operating member is connected to the operating hose 4. By operating the operating member, medical personnel can control the firing of the separate closure clamps 10 by driving the operating hose 4. The operating member is a conventional mechanism and is not shown in the figure. The mechanism and operation of the operating member will not be described in detail in the following embodiments. The elastic hose 5 is wrapped around the operating hose 4. An adapter ring 51 is provided at one end of the elastic hose 5. The adapter ring 51 is used to connect to the separate closure clamp 10. The elastic hose 5 facilitates insertion into the human body and bending and feeding.

[0065] See Figure 8 、 Figure 9 and Figure 10 As shown, the first latching member 16 of one of the adjacent outer sleeves 1 is latched onto the second latching member 17 of another adjacent outer sleeve 1. The twisted and twisted multi-core stranded wire 3A formed by the plurality of control wires 3 has a first end 31A and a second end 32A. The end of each control wire 3 is bent back at a different distance from the first end 31A toward the second end 32A. A plurality of connecting portions 31 extending at intervals from near the first end 31A toward the second end 32A are formed by the end of each control wire 3. These connecting portions 31 can be connected to the jaw assembly 2 of the sequentially connected separate closure clips 10 via the spaced-apart connecting portions 31.

[0066] See Figure 11 and Figure 12 As shown, there is a third latching member 511 on the adapter ring 51 of the elastic hose 5. Among the serially connected separate closing clamps 10, the second latching member 17 of the outer sleeve 1 of the last separate closing clamp 10 is latched on the third latching member 511 of the adapter ring 51, and the above-mentioned multi-core stranded wire 3A extends into the operating hose 4, so that each separate closing clamp 10 can be driven effectively by the operating hose 4. The operating hose 4 can usually use a Teflon hose, which not only increases the pushing performance, but also drives the multi-core stranded wire 3A to push and fire, and prevents the multi-core stranded wire 3A from being scattered.

[0067] See Figure 13 and Figure 14 As shown, when the split closure clip 10 is fired, the two clips 22 extend out of the outer sleeve 1 until the operating portions 222 of the two clips 22 press against the two retaining walls 14, causing the two clips 22 to pivot relative to each other and open, and the release rope 23 is extended through the extension section 231. Figure 15 and Figure 16As shown, the multi-core stranded wire 3A is then retracted to pull the control wire 3 backward, causing the two clips 22 to pivot closed again, and the operating portions 222 of the two clips 22 to pass over the two elastic stoppers 15 and be stopped by the two elastic stoppers 15, preventing the two clips 22 from extending out of the outer sleeve 1 again and pivoting open. At the same time, the release rope 23 is pulled backward and tightened. Figure 17 As shown, the multi-core twisted wire 3A is continuously retracted to cause the control wire 3 to be continuously pulled backward. At this time, the release rope 23 is continuously pulled backward to pull the second latch 17 toward the relative inner side to disengage from the first latch 16 and release the latching state. The pulling force of the control wire 3 causes a reaction force to accumulate on the connecting portion 31 of the control wire 3, causing the stress of the connecting portion 31 to concentrate and break from the connecting rod 212 of the connecting member 21, completing the firing of the separate closing clip 10.

[0068] See Figure 18 As shown, since the connection portion 31 of each control line 3 on the multi-core twisted wire 3A is bent back at different distances from the first end 31A to the second end 32A of the multi-core twisted wire 3A, the control line 3 of the separated closing clamp after firing can be retracted by retracting the multi-core twisted wire 3A, so that the connection portion 31 of the control line 3 of the adjacent unfired separated closing clamp 10 can be located at the frontmost firing position, and the control line 3 of the separated closing clamp 10 after firing will not interfere with the adjacent unfired separated closing clamp 10, so repeated operations can complete the continuous firing of the separated closing clamp 10.

[0069] The above description is only illustrative of the present invention and not restrictive. Those skilled in the art will understand that many modifications, changes or equivalents may be made without departing from the spirit and scope defined by the claims, and all of them will fall within the scope of protection of the present invention.
