Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a novel surgical retractor. Background Art

[0002] A surgical retractor is a medical device used to assist medical staff in handling and manipulating tissues, instruments or other items during surgery. It is usually made of stainless steel or other medical-grade materials, with a certain length and curved shape, so that medical staff can perform precise operations during surgery. With the development of urbanization, technology and humanization, the healthcare industry has been booming. In some surgeries involving subcutaneous tissue and muscles, retractors are needed to pull apart subcutaneous tissue or muscles to expose a larger surgical field, thereby reducing the difficulty of surgery and increasing the success rate of surgery.

[0003] The surgical retractors on the market are usually one-piece retractors, and the handle of the retractor cannot be adjusted freely, so it can only be pulled by the assistant's hand. However, the assistant assisting in each operation may not be the same person, and different assistants have different body shapes, so that the existing retractors cannot adapt to different assistants, and the assistants cannot maintain the most comfortable angle during traction, which can easily cause physical discomfort to the assistants due to poor pulling posture, thereby affecting the retractor's pulling effect on subcutaneous tissue or muscle, thereby reducing the distraction effect during surgery and the surgical effect. For this reason, we propose a new surgical retractor. Utility Model Content

[0004] The main purpose of the utility model is to provide a novel surgical retractor, which can effectively solve the problems in the background technology.

[0006] Preferably, the connecting assembly includes a clamping hole opened at the end of the first handle rod and a clamping block fixedly connected to the end of the second handle, and the clamping block is adapted to the clamping hole, and the outer wall of the clamping hole is threadedly connected with a fastening bolt, and the end of the fastening bolt extends into the inner cavity of the clamping groove and extends into the interior of the clamping block.

[0007] Preferably, the outer side wall of the connector is provided with a second threaded connection hole.

[0008] Preferably, the end surfaces of the connecting rods are all provided with external threads adapted to the second threaded connecting holes.

[0009] Preferably, anti-slip bumps are fixedly connected to the surfaces of the first handle bar and the second handle bar.

[0010] Preferably, the hook heads are all double hook heads.

[0011] Preferably, the hook head and the hook handle are both made of stainless steel.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model provides a connecting head, a threaded rod, a first threaded connecting hole and a connecting assembly to cooperate with each other, and twist the connecting head forward and backward so that the connecting head drives the threaded rod to move forward and backward in the first connecting hole opened inside the handle rod, thereby extending the length of the hook handle, so that the hook handle can be adjusted in length according to needs, and at the same time twist the fastening bolt outward so that the fastening bolt is separated from the clamping block, so that the clamping block can drive the second handle rod to rotate in the clamping groove of the first handle rod, and the angle between the first handle rod and the second handle rod can be changed according to needs, thereby adjusting the angle of the hook head, and tightening the fastening bolt after adjustment, so that the retractor can be used to adapt to different surgical assistants, so that the surgical assistant can maintain the most comfortable posture to pull the retractor when assisting the doctor in surgery, ensuring the pulling effect while effectively cooperating with the doctor to achieve a long-term surgery, thereby improving the success rate of the surgery.

[0014] 2. The utility model cooperates with each other through the connecting head, the second threaded hole, the connecting rod and the external thread. The hook head is threadedly connected to the second threaded connecting hole provided in the outer wall of the connecting head through the external thread provided on the surface of the end of the connecting rod. In this way, the hook head equipped with the connecting rod can be disassembled from the hook handle at any time. In this way, different hook heads can be replaced according to needs during surgery, so as to adapt to the use of pulling the skin in different surgical situations, effectively reduce the limitations of the use of the retractor, and effectively improve the practical effect of the retractor.
