Abstract
The utility model relates to a surgical instrument, which mainly relates to a nerve retractor used for separating the implication between the nerve and surrounding tissues during operation. A circular arc plate is formed by a draw open end, a transition section and a hand-hold end. The draw open end, the transition section and the hand-hold end change transversely and continuously from narrow to wide. The draw open end is a circular arc end head, and simultaneously the surfaces of the draw open end, the transition section and the hand-hold end are non-reflecting light grey black. Thereby, the nerve can be safely drawn open, the operation can not be affected by the operation light.
Description
Technical field this utility model relates to a kind of operation tool, specifically is meant the separately neural nerve retractor that involves with surrounding tissue in the operation.
Background technology is present, in the microneurosurgery operation, often use little detacher, tweezers, instruments such as little drag hook retract nervous tissue, but this class instrument one be nonelastic can not be crooked, damage nerve easily and influence appearing of operating field, the 2nd, the surface of this class instrument all is silvery white reflective surface, and under the light-illuminating of operation, influence retracts neural action.
The summary of the invention the purpose of this utility model is to overcome above-mentioned shortcoming, provides a kind of and can retract nerve safely, again the micro-nerve retractor of not operating because of the operating lamp influence of light.
The technical solution of the utility model is: it be laterally from narrow to wide continually varying retract the elasticity arc plate that end, changeover portion and handheld terminal form, and retract end, handheld terminal is all the circular arc termination; Retract end, changeover portion and handheld terminal and be all holistic grey black Ti-Ni alloy plate, and outer surface all is provided with not reflector layer of grey black.
Because the trapezoidal arcuation thin plate of this utility model changeover portion can damaged with the human nerve that keeps the good springiness up and down of narrow end, make desiring to retract.In addition,, the light of the houselights in the operation is played Absorption, do not produce reflectively, can not have influence on the operation of operation because this utility model is provided with not reflector layer of grey black.
Appended drawings is a structural representation of the present utility model.
Specific embodiment this utility model is the arc thin elastic plate of surperficial grey black, as grey black Ti-Ni alloy plate, it be laterally from narrow to wide continually varying retract end (1), changeover portion (2) and handheld terminal (3) three parts and become a trapezoidal arc, wherein retract end (1) and handheld terminal (3) is all the circular arc termination, retract the arc diameter 2-6mm of end (1), to adapt to the needs that operating field varies in size, prevent the nerve of damaging, the about 2cm of arc diameter of handheld terminal (3) grips so that be suitable for finger.During use, finger is pinched the handheld terminal (3) of retractor, affect the intravital nerve of people from bottom to top, the nerve that is affected is subjected to involving of tissue such as muscle, blood vessel on every side, the inner pulling force that keeps involving state that exists, prevention retracts end (1) and upwards affects, because retracting end (1) has better elastic, not easy damaged or the disconnection of nerve that is affected is along with handheld terminal (3) repeatedly affects from bottom to top, just can reach safely and separate with surrounding tissue, so that proceed operation neural.
Claims (3)
1, a kind of micro-nerve retractor is characterized in that: it be laterally from narrow to wide continually varying retract the elasticity arc plate that end (1), changeover portion (2) and handheld terminal (3) form, and retract end (1) and handheld terminal (3) is all the circular arc termination.
2, micro-nerve retractor according to claim 1 is characterized in that: it retracts end (1), changeover portion (2) and handheld terminal (3) outer surface and all is provided with not reflector layer of grey black.
3, micro-nerve retractor according to claim 1 is characterized in that: it retracts end (1), changeover portion (2) and handheld terminal (3) and is all holistic grey black Ti-Ni alloy plate.
