Description
Technical Field
The utility model relates to the technical field of medical appliances, in particular to a disposable tissue closing clamp base.
Background
Clip appliers are commonly used medical devices, and are commonly used in needle-holding suturing procedures for grasping blood vessels and performing a hemostatic function, and are sometimes referred to as hemostats. In medical operations, especially in minimally invasive techniques, after a patient takes a hemostatic drug in the event of bleeding, the vascular aorta is clamped by a clip applier, and the blood is prevented from flowing out. The clip applier is on the same principle as the clip, but is sterilized. The clip applier has large, small, toothed, toothless, straight and curved parts. Different types of clip appliers are selected according to different operation positions.
The clip applier is used during a surgical procedure, for example, by first applying the clip to a site or site of possible bleeding or a site of bleeding that has been found. Thus, the accuracy of the clamping of the bleeding point is required, preferably once, without excessive carryover into healthy tissue. Because the operation space of the minimally invasive surgery is narrow and complex, the use stroke of the instrument is small, and the precision requirement is high.
The final purpose of the clip applier is to deliver a disposable tissue closure clip to the hemostatic portion and clamp the clip through the disposable tissue closure clip to provide hemostasis. However, conventional clip appliers are only equipped with a closure clip. However, during a surgical procedure, typically not only one vessel needs to be clamped for hemostasis, but two or three, or even more vessels. The existing clip applier can only carry one plastic clip, and the clip is disposable.

The detailed structure of the bottom wall 325 of the support outer base 32 refers to the structure of the fixing base 23 and the supporting position 24 in fig. 4, and the principle and structure of the bottom wall 325 and the top of the fixing base 23 for supporting the closing clip are basically the same, except that the placement direction is different, on the fixing base 23 of the fixing clip base 20, the supporting position 24 of the fixing base 23 is upward and extends from the top frame, while the bottom wall 325 is bottom and extends from the bottom edge of the support outer base 32 (see fig. 2). The second support assembly includes the second support column 13 and the support outer base 32, and may further include a clamping groove 315.
The bottom surface of the base of the disposable tissue closing clamp base 100 is further adhered with an adhesive layer, and a release paper layer is adhered outside the adhesive layer. In use, the release paper is removed and the base 100 is adhered to a table such as an operating table by means of an adhesive layer, the base 100 having been provided with the first and second closure clips 60', 60 when applied. Taking the clip applier shown in fig. 8 as an example, referring to fig. 1, 2 and 7, after the base 100 is fixed, the clip applier head 3 is first seated on the support seat 317, at this time, the storage compartment 51 may be fixed or properly extended, the clip applier continues to force downward, the slide clip holder 30 slides downward, and of course, the slide clip holder 30 is allowed to slide downward when the clip applier head 3 is just inserted, and the storage compartment 51 is pushed simultaneously when sliding downward, so that the storage compartment 51 extends out of the clip applier head 3 and extends out of the storage compartment 51 to the maximum extent, when sliding to the bottom, the slide clip holder 30 slides over the anti-back hook 126 and the anti-back hook 126 is snapped back into the slide clip holder 30, and at the same time, the second closing clip 60 is loaded into the storage compartment 51, so that when the snap is heard, the second closing clip 60 is already loaded into place in the storage compartment 51. This is the first second closing clip 60 loading process. Then, following the same procedure as described above, the clip applier then loads a second closure clip 60 from another slide clip seat 30, and in turn if there are more slide clip seats 30. After the second closure clip 60 is completely loaded on the entire slide clip seat 30, the first closure clip 60' is then loaded, and the loading process is described below with reference to fig. 3: the binding clip 3 of the second closing clip 60 is inserted directly through the supporting position 24 of the thinner fixing seat 23, and the binding clip 3 moves downwards along the guiding surface 215, and simultaneously the convex ribs 62 of the outer protruding arms of the first closing clip 60' are wedged into corresponding grooves or holes of the binding clip 3, so that the first closing clip 60' is placed at the jaw position of the binding clip 3, and the first closing clip 60' is in a free open state, but not in the storage cabin 51. Of course, in other embodiments, it is also possible to continue to move the binding clip 3 downwards to load the first closure clip 60' into the storage compartment 51. The free open position of the first closure clip 60 'in this embodiment is placed at the jaw position of the binding clip 3 to facilitate direct clamping of the vessel during surgery without pushing on the one closure clip 60'. Thus, the filling of 1+N closed clamps is completed, the continuous clamp can be continuously used during operation, and the continuous clamp vascular operation of the continuous clamp forceps can be well matched.
The disposable tissue closing clip base 100 is provided with the fixing clip base 20 and the sliding clip base 30, wherein the fixing clip base 20 can be used for fixing the first closing clip 60', and the first closing clip 60' is usually located at the periphery of the clip applier and is in a free open state, so that the base adopts the fixing clip base 20, and the structure of the base not only plays a role in fixing, but also facilitates the clip applier to clip the closing clip from the fixing clip base 20. Moreover, by providing a predetermined number of slide clamp bases 30 to accommodate a plurality of second closure clamps 60 that are not external, because the plurality of second closure clamps 60 are in a compressed state in the clip applier, the base has more than one cavity 12, one of the slide clamp bases 30 is provided in each cavity 12, the side walls of each cavity 12 define slide guiding structures that guide the slide clamp bases 30, the slide clamp bases 30 slide into the bottom of the cavity 12 through the slide guiding structures, thus allowing the clip heads to have a certain stroke when the clip applier is loaded, and the plurality of second closure clamps 60 are compressively accommodated in the clip applier by the cooperation of the clip applier with the slide clamp bases and the second support assemblies. Therefore, the disposable tissue closing clamp base solves the defect that the traditional clamp base cannot be used for loading the closing clamp in a compressed state, and the second closing clamp 60 can be rapidly and accurately loaded in the clamp applying clamp in a compressed mode only by matching the clamping action and the pushing function of the clamp applying clamp, so that the operation efficiency is improved, and the medical time is saved.
It should be noted that the present utility model is not limited to the above embodiments, and those skilled in the art can make other changes according to the inventive spirit of the present utility model, and these changes according to the inventive spirit of the present utility model should be included in the scope of the present utility model as claimed.
