Description

Technical Field

[0001] The present invention relates to surgical instruments, in particular to detachable surgical clip appliers. Background Art

[0002] Clip appliers are commonly used instruments during surgery. They usually consist of a clamp head and a handle, and the clamp head is driven by the opening and closing of the handle.

[0003] The connection between the clamp head and the handle of the currently used clip appliers is relatively simple, usually a fixed connection that cannot be easily disassembled. The clamp head is the part that is directly used, and it is more likely to be worn out than the handle and other parts due to frequent use. Once the clamp head is worn out, it is usually discarded, otherwise it will easily cause problems and surgical accidents if it is continued to be used.

[0004] Because the clamp head and handle of the existing clamp applier are usually inconvenient to disassemble, they can only be discarded as a whole when discarded, resulting in a high cost of the clamp applier; and the handle and other parts of the clamp applier are not as easy to wear as the clamp head, and discarding these usable parts together with the clamp head is bound to be a waste of resources.

[0005] It is of great significance to design a clamp applier with a clamp head that is easy to disassemble and replace to solve the above problems. Summary of the invention

[0006] The object of the present invention is to provide a detachable clip applier for surgery, which has the advantages of convenient detachment and replacement of the clamp head and relatively low use cost.

[0010] In the aforementioned detachable surgical clamp, the rotating wheel is provided with a rotating wheel insert and a gear sleeved on a mounting tube; the rear end of the rotating wheel is sleeved with a rear cover; a flush valve is provided on the upper front side of the rotating wheel, and a flow channel corresponding to the flush valve is opened in the rotating wheel.

[0011] In the aforementioned detachable clip applier for surgery, the front end of the push rod joint is connected to the clamp head through the clamp head clip.

[0012] In the aforementioned detachable surgical clamp, the clamp rod socket is hollow, and a flow channel for flushing is provided above the rear end of the clamp rod socket; the clamp rod joint is hollow, and the rear end of the clamp rod joint is conical; the threaded rod and the clamp rod joint are detachably connected by means including threaded connection; the clamp rod joint is sleeved on the rear end of the push rod.

[0013] Compared with the prior art, the present invention is composed of a pliers head, a pliers rod, a handle, a driving member and a connecting member, wherein the connecting member is detachably connected to the pliers head and the driving member respectively; the connecting member includes a push rod, a push rod joint and a pliers rod joint, the driving member includes a threaded rod and a threaded rod seat, a corresponding pliers rod socket is provided at the front end of the threaded rod, and the pliers rod joint is detachably connected to the threaded rod, thereby facilitating disassembly and replacement; the pliers head itself is also connected to the push rod by a push rod joint, and the push rod joint is connected to the push rod by a detachable sleeve connection, thereby facilitating disassembly;

[0014] By adopting the present application, the clamp head can be disassembled conveniently and quickly according to actual needs, so that the damaged clamp head can be replaced without scrapping the entire clamp applicator, and the use cost is relatively low.

[0015] Therefore, the present invention has the advantages that the pliers head can be easily disassembled and replaced and the use cost is relatively low. BRIEF DESCRIPTION OF THE DRAWINGS
