Abstract

The dura mater continuous suturing device comprises a suturing head, the suturing head comprises a needle inserting device, a clamping device and a thread hooking device, the clamping device is composed of a clamping plate, the dura mater continuous suturing device further comprises an operator, the operator comprises a needle inserting switch and a clamping switch, a connecting cylinder is arranged between the suturing head and the operator, and the needle inserting switch comprises a first grip and a second grip. The first grip is fixedly connected with the connecting cylinder, the upper end of the second grip is hinged to the upper end of the first grip, the second grip is connected with the thread hooking device through the first transmission mechanism, the clamping switch is hinged to the connecting cylinder, and one end of the clamping switch is connected with the clamping device through the second transmission mechanism. According to the dura mater continuous suturing device, the time-saving, labor-saving, safe and reliable continuous suturing device is provided for existing suturing operation of the dura mater, the structure is simple, the production cost is low, extra consumable expenditure is reduced, and the dura mater continuous suturing device can be applied to clinical application on a large scale.

Description

technical field [0001] The invention relates to articles for human life, in particular to a medical device, in particular to a dura mater continuous suturing device. Background technique [0002] The dura mater is a relatively tough membrane structure covering the outermost layer of brain tissue, which plays the most basic mechanical protection role for brain tissue. The integrity of its structure can prevent the occurrence of cerebrospinal fluid leakage and reduce the occurrence of intracranial infection, epilepsy and other diseases. For neurosurgery, dura mater incision is the only way to enter the brain for surgery, so the dura mater must be tightly sutured and repaired at the end of the operation to prevent postoperative cerebrospinal fluid leakage, subcutaneous effusion, intracranial infection, and epilepsy and so on. In the prior art, suturing of the dura mater is performed manually by needle and thread. [0003] At present, there is a type of suture-free dura mater...
