Description

Technical Field

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

[0002] Traditional microsurgery techniques are mainly used in orthopedics and plastic surgery. With the development of technology, they are also widely used in neurosurgery, otolaryngology, ophthalmology, etc. Microsurgery requires high precision in operation, so the use of microsurgical instruments is crucial. Retractors are common instruments in surgery. They can be used to open the incision and expose the surgical field to facilitate surgical operations. Microsurgical retractors require a more delicate and compact structure.

[0003] The retractor body of a traditional microsurgical retractor is formed by bending a metal wire, and a connecting hook is provided at the tail of the retractor body. The connecting hook is a cone with a barb at the tail end. The above-mentioned traditional microsurgical retractor structure has the following shortcomings: (1) The retractor head is formed by bending a metal wire, which is not enough to support a large pulling force, and is easily deformed during surgery, causing great inconvenience to the surgery; (2) The head of the retractor head is not smooth enough, and does not have good protection for the retraction and release of nerves or blood vessels. After the head end is hooked into the muscle, it puts pressure on the muscle, and in the process of changing the angle of the retractor, it may damage the blood vessels and nerves accompanying the muscle; (3) The surgeon needs to manually retract the hook, and often has to maintain the same posture for a long time or change the angle and strength of the retractor, which cannot free the surgeon's hands, which is not conducive to the operation; (4) The traditional microsurgical retractor can only be used once, and needs to be purchased repeatedly in large quantities, resulting in excessive consumption of materials and waste of environmental resources.

And as a solid self-lubricating material, the carbon fiber composite material not only has good tissue compatibility, but also has good wear resistance and low friction coefficient, which increases practicality.

[0012] The head of the retractor is designed to be arc-shaped, which reduces the damage to the blood vessels and nerves around the muscles; the retractor head is provided with a semi-circular arc structure to prevent muscle damage, which increases the contact area with the muscle, reduces the pressure of the retractor on the muscle, and minimizes the damage to the muscle. The retractor handle is made of silicone material. The elastic material enables the existing hemostatic forceps to directly fix the retractor on the surgical drape, freeing the hands of the surgeon. At the same time, silicone can withstand high temperature and high pressure, can be repeatedly sterilized and used, and is not easy to deform.

[0013] The retractor head and the retractor handle are made of high temperature and high pressure resistant materials, which can be sterilized and reused together with common surgical instruments, and have good practicality.
