Description

Technical Field

[0001] The utility model relates to a continuously firing device for medical clamps, in particular to a device in which a plurality of handles are arranged on the main body of the firing device, and each handle is connected to a corresponding control line, so that each handle can control the firing of each medical clamp. Background Art

[0002] Medical clamps, such as hemostatic clips, can be used to close and stop bleeding at the affected part of the body under the guidance of an endoscope. However, when the affected part is large, multiple hemostatic clips may need to be used simultaneously.

[0003] The hemostatic clip is fired by pulling the control line, and the firing method can be described in relevant previous cases such as Chinese Patent No. CN116831682A "Hemostatic Clip Structure" and Chinese Patent No. CN116211385A "Continuous Closing Clip with Multiple Control Lines".

[0004] The firing mechanism capable of firing multiple hemostatic clips continuously is described in, for example, Chinese Patent No. CN209301227U “Handle assembly for a continuous firing hemostatic clip device” or Chinese Patent No. CN213665529U “A continuous multiple firing minimally invasive vascular closure device”.

[0005] In the case of CN209301227U, the handle assembly includes a gear handle rod, an adjustment handle rod and a finger-lock slip ring. The gear handle rod is provided with an adjustment section, and the adjustment section is provided with a plurality of gear adjustment holes. The adjustment handle rod is sleeved on the adjustment section of the gear handle rod, and the finger-lock slip ring is slidably arranged on the adjustment handle rod. The finger-lock slip ring also has a second connection portion connected to a pull cable (control line), and the demand for continuous firing of hemostatic clips can be met through multiple gear adjustments.

[0006] In the case of CN213665529U, the continuous multiple-shot minimally invasive vascular closure device uses a rack meshing transmission to continuously fire the hemostatic clips.

[0007] The hemostatic clip firing devices of the above-mentioned CN209301227U, CN213665529U and other previous cases only use one firing handle to continuously fire the hemostatic clips. In this way, after the current hemostatic clip is fired, it is necessary to set the adjustment gear of the adjustment section / adjustment hole or use a conversion mechanism such as rack engagement to connect and control the firing of different hemostatic clips. The mechanism is relatively complicated and there is a problem that the conversion mechanism may get stuck and the subsequent hemostatic clips cannot be fired. Utility Model Content

[0008] Therefore, in order to achieve stable firing of a continuously firing hemostatic clip, the purpose of the present invention is to provide a continuously firing device for a medical clamp.

[0009] The utility model provides a continuous firing device for a medical clamp, comprising:

[0010] A body is provided with a plurality of guide grooves extending along an axial direction and recessed from the outer surface of the body. A plurality of control wires are inserted into and installed on the body, and each of the plurality of control wires is connected to a medical clamp. A plurality of handles are installed in the guide grooves of the body and can move along the axial direction, and each of the plurality of handles is connected to one of the control wires.

[0011] Furthermore, the main body is in the shape of an elongated handle extending along the axial direction, and a protruding stop portion is provided at the end of the main body.

[0012] Furthermore, the main body has three guide grooves which are distributed 120 degrees apart on the axial circumference, and three corresponding control lines and three handles are installed on the main body.

[0013] Furthermore, two opposite ribs are formed in the guide groove, and two opposite grooves are formed on the handle. The handle extends into the guide groove and the two ribs extend into the two grooves, so that the handle is installed in the guide groove of the body.

[0014] Furthermore, the control line extends into the handle, and a fastener is provided in the handle to fasten the control line.

[0015] Furthermore, the handle includes a base and a handle piece, the base is installed in the guide groove, and the handle piece is pivotally connected to the base so that the handle piece can be pivoted relative to the base and lie on the body.

[0016] The following effects can be achieved according to the above technical features:

[0017] 1. The utility model uses multiple handles to respectively fire corresponding medical clamps, and does not need to set a conversion mechanism to connect and control the firing of different hemostatic clamps, and has a simple structure.

[0018] 2. The utility model uses multiple handles to fire corresponding medical clamps respectively, which reduces the problem of jamming and inability to fire compared to using a single firing handle to fire multiple medical clamps.

[0019] 3. A raised stopper is set at the end of the body to increase the coverage of the handheld device and prevent accidental slipping during operation.

[0020] 4. The handle can be pivoted and laid flat for easy storage. BRIEF DESCRIPTION OF THE DRAWINGS

In this embodiment, there are three guide grooves 11 on the main body 1, which are distributed at intervals of 120 degrees on the circumference of the axial direction P, and a protruding stopper 12 is provided at the end of the main body 1. A plurality of control wires 2 and a plurality of handles 3. In the present embodiment, there are three control wires 2 and three handles 3 corresponding to the three guide grooves 11 of the main body 1. The rear ends of the control wires 2 extend into and are mounted on the main body 1, and the front ends of the control wires 2 are respectively connected to a medical clamp and extend out of the main body 1, and are then wrapped with an elastic hose 4 (the medical clamp is, for example, a hemostatic clamp, and the medical clamp is connected to the control wire 2 and is fired to be detached from the control wire 2 in the conventional manner as mentioned above, but not in the improved manner of the present case, so the medical clamp is not drawn in the figure). The handles 3 are respectively connected to one of the control wires 2 and are mounted in the guide grooves 11 of the main body 1, so that the control wire 2 can be controlled by the handles 3 to move along the axial direction P to fire the medical clamp.

[0033] See also Figure 4 and Figure 5 As shown, the present embodiment specifically extends the control line 2 into the handle 3, and a fastener 32 is provided in the handle 3 to fasten the control line 2 and fix the control line 2 on the handle 3, two opposite convex ribs 111 are formed in the guide groove 11 of the main body 1, and two opposite grooves 31 are formed on the handle 3. When the handle 3 is extended into the guide groove 11, the two convex ribs 111 are extended into the two grooves 31, thereby installing the handle 3 in the guide groove 11 of the main body 1.

[0034] See also Figure 6 and Figure 7 As shown, when the medical clamp is to be fired, the handle 3 is pushed forward along the guide groove 11 so that the control line 2 (such as Figure 4 , Figure 5 The medical clamp is extended from the front end of the elastic hose 4 and opened (not shown in the figure), and then the handle 3 is pulled back along the guide groove 11 to close the medical clamp and disengage the control line 2 to complete the firing. The three handles 3 are operated in sequence to complete the continuous firing of three medical clamps. The handle 3 that has completed the firing is withdrawn to the end of the guide groove 11 to avoid interfering with the operation of other handles 3. The stopper 12 can increase the covering property of the body 1 when holding it, and prevent the hand from slipping accidentally during operation.

[0035] See also Figure 8 and Fig. 9As shown, it is another embodiment of the continuous firing device of the medical clamp of the utility model. Further, the handle 3 includes a base 33 and a handle member 34. The base 33 is installed in the guide groove 11. The handle member 34 is pivotally connected to the base 33 so that the handle member 34 can be pivoted relative to the base 33 and lie on the main body 1 for easy storage.
