Abstract
The utility model discloses a disposable indwelling nerve plexus stimulation needle which comprises a stylet, wherein the stylet is connected with a connector of a stimulation instrument through a connecting wire; the connector of the stimulation instrument is connected with an external nerve stimulator; a stylet insulation handle is arranged at the connection part of the stylet and the connecting wire; and an outer cannula is sleeved on the external surface of the stylet. The disposable indwelling nerve plexus stimulation needle has the beneficial effects that materials are convenient to draw, cost is low, and cost performance is high; and meanwhile, a needle point is of a short inclined plane, and an included angle between the needle point and the longitudinal axis is 30 degrees, the direct damage on the peripheral nerve can be reduced, the needle diameter is thinner, and leakage is not easy to occur after the cannula is indwelled, so the hurt to a patient is reduced, the patient easily accepts the needle, and the continuous nerve block and/or postoperative analgesia after indwelling the cannula is relieved.
Description
Technical field
This utility model belongs to technical field of medical instruments, and relating to a kind of disposable plexus nervorum of keeping somewhere stimulates pin.
Background technology
The existing plexus nervorum of keeping somewhere stimulates pin to cost an arm and a leg, complex operation, and also needle point is more blunt, is difficult for broken skin; Damage to patient in the piercing process is big, and puncture successfully withdraw from pillow core and keep somewhere outer catheter after pinprick lasting oozing of blood sepage is often arranged.
Summary of the invention
The purpose of this utility model provides a kind of disposable plexus nervorum of keeping somewhere stimulates pin, has solved the problem big to patient trauma, and simple to operate, cheap.
The technical scheme that this utility model adopted is; The disposable plexus nervorum of keeping somewhere stimulates pin; Comprise nook closing member, nook closing member is connected with stimulating the appearance connector through connecting line, stimulates the appearance connector to be connected with outside nerve stimulation appearance; The position that nook closing member is connected with connecting line is provided with nook closing member insulation handle, and the outer surface of nook closing member is with trocar sheath.
The characteristic of this utility model also is,
Nook closing member is outside equipped with the trocar sheath needle handle that is connected with trocar sheath.
The needle point of nook closing member has 30 ° of angles for short inclined-plane and with the longitudinal axis of nook closing member.
Trocar sheath is than the short 3cm of nook closing member.
The beneficial effect of this utility model is to draw materials easyly, with low cost, and cost performance is high; Needle point, can reduce perineural coup injury with 30 ° of longitudinal axis angles for short inclined-plane simultaneously; The diameter of pin is thinner, is difficult for behind the inlying catheter oozing out, and has reduced the infringement to patient; Patient is acceptant, is easy to nerve block and/or postoperative analgesia continuously behind the inlying catheter.

Among the figure, 1. trocar sheath, 2. trocar sheath needle handle, 3. nook closing member, 4. connecting line, 5. nook closing member insulation handle 6. stimulates appearance connector, 7. trocar sheath needle handle connector, 8. syringe connector, 9. trocar sheath connection tube.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment this utility model is elaborated.
The disposable structure of keeping somewhere plexus nervorum stimulation pin of this utility model; As shown in Figure 1, comprise nook closing member 3, the needle point of nook closing member 3 has 30 ° of angles for short inclined-plane and with the longitudinal axis of nook closing member 3; Nook closing member 3 is connected with stimulating appearance connector 6 through connecting line 4; Stimulate appearance connector 6 to be connected with outside nerve stimulation appearance, the position that nook closing member 3 is connected with connecting line 4 is provided with the nook closing member handle 5 that insulate, and is with trocar sheath 1 at the outer surface of nook closing member 3; Also be provided with the trocar sheath needle handle 2 that is connected with trocar sheath 1 outside the nook closing member 3, the structure of trocar sheath 1 is as shown in Figure 2.Trocar sheath 1 is than nook closing member 3 short 3cm.
The disposable plexus nervorum of keeping somewhere of this utility model stimulates the use of pin to be; Trocar sheath 1 is placed in outside the nook closing member 3 before puncture; The stimulation appearance connector 6 of tail end connects the nerve stimulation appearance; Sustainable radiation pulse current carries out effective impulse stimulation to nerve, and the neural muscle of arranging the zone can produce corresponding contraction.To be positioned accurately, confirm that good institute blocks the position of nerve after, fix the direction and the degree of depth of needle body, fixedly nook closing member 3 is motionless; Trocar sheath 1 is sent into subcutaneous 1.5cm-3cm depths along the puncture direction of nook closing member 3, pull out nook closing member 3, fixed jacket pipe 1, the tail end of trocar sheath 1 connects trocar sheath connection tube 9 again; Trocar sheath connection tube 9 is connected with the tail end of trocar sheath 1 through trocar sheath needle handle connector 7, and trocar sheath connection tube 9 other ends connect syringe through syringe connector 8, and are as shown in Figure 3, after tail end connects syringe; Injection liquid, the continuous nerve block of row eases pain like the need postoperative; Keep trocar sheath 1, remove syringe, connect the analgesia pump postoperative and ease pain continuously.Because trocar sheath 1 has reduced the needle body diameter than nook closing member 3 short 3cm, when nerve is sought in the puncture location again, reduced damage to tissue.
