Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, and in particular relates to an isolation clamp. Background Technology

[0002] Currently, during surgical procedures, it is necessary to isolate the tissues near the surgical target to facilitate surgical treatment by medical staff.

[0003] Existing isolation methods typically include physical isolation, liquid isolation, and gas isolation. For example, physical isolation often involves using dissecting forceps to separate the tissues surrounding the surgical target organ, reducing intraoperative damage. However, using dissecting forceps results in a small separation area for the surrounding tissues, and multiple dissecting forceps are required when there is a large amount of tissue to isolate. This not only increases the difficulty of the operation for medical staff but also increases the possibility of damage to other tissues during the operation.

[0004] To address these issues, we provide an isolation clamp. Utility Model Content

[0005] The purpose of this invention is to provide an isolation forceps that, through the coordinated arrangement of isolation components and control components, solves the problem that in the prior art, multiple separation forceps are required during surgical isolation operations, which not only increases the difficulty of operation for medical personnel but also easily causes damage to surrounding tissues.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is an isolation clamp, including a long rod, an isolation component and a control component. The inner cavity of the long rod is provided with a pull rod, and the left side of the pull rod surface is provided with a first thread.

[0008] The isolation assembly is located on the right side of the long rod and includes an isolation membrane. The front and rear sides of the bottom of the isolation membrane are provided with clamp heads. A blade is fixedly connected to the left side of the clamp head. A connecting rod is movably connected to the left side of the blade. The opposite sides of the two blades are movably connected to the long rod through a rotating shaft. The right sides of the top and bottom of the pull rod are movably connected to the connecting rod.

[0009] The control component is located on the left side of the long rod and includes a positioning ring. The right side of the positioning ring extends into the inner cavity of the long rod. A knob is fitted on the surface of the positioning ring, and a second thread is formed on the inner wall of the knob to cooperate with the first thread.

[0010] The present invention is further configured such that the front and rear sides of the bottom of the isolation membrane are fixedly connected to the clamp head by a thin film buckle, and the clamp head is J-shaped with an arc surface at its right end.

[0011] The present invention is further configured such that the material of the isolation membrane is an elastic plastic film, and the right sides of the top and bottom of the pull rod are movably connected to the connecting rod through bearings.

[0012] The present invention is further configured such that a connecting groove is provided on the left side of the blade, and the top and bottom of the connecting rod are movably connected to the inner wall of the connecting groove by a pin.

[0013] The present invention is further provided that the surface of the knob is provided with an anti-slip groove, and the surface of the positioning ring is provided with an annular notch for use with the knob.

[0014] The present invention is further configured such that a square through hole is provided on the right side of the positioning ring for use with the pull rod, and the surface of the pull rod is slidably connected to the square through hole.

[0015] The present invention is further configured such that the front and rear sides of the right side of the long rod are provided with movable notches for use with the blade and the connecting rod, the isolation membrane is trapezoidal in shape, and the front and rear sides of the top of the isolation membrane are provided with mounting holes.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model, through the setting of the isolation component, can control the movement of the connecting rod and the blade through the cooperation of the pin and the pull rod, so that the blade drives the two forceps to open, and controls the expansion of the isolation membrane by moving the forceps. The isolation membrane is used to isolate the tissue around the surgical target organ. Since the isolation is carried out through the isolation membrane, the isolation range is large, and there is no need to use multiple separation forceps, which reduces the difficulty of operation during the operation and also reduces the possibility of intraoperative damage.

[0018] 2. Through the setting of the control component, the present invention allows medical staff to rotate the knob. The second thread on the inner wall of the knob engages with the first thread on the surface of the pull rod, so that the rotation of the knob can drive the pull rod to move. When the pull rod moves, it can control the movement of the connecting rod, thereby controlling the two clamp heads and making it convenient for medical staff to operate the expansion and contraction of the isolation membrane.
