Abstract

The utility model discloses a multi-functional intracranial hematoma puncture draining trocar. A draining cannula is a three-way needle body and is provided with a side draining opening, length and direction scale marks are arranged on the outer wall of the draining cannula and the outer wall of a draining tube, the front tip of the draining cannula is enclosed, a guide opening is arranged at the bottom end, which is 90 degrees of an arc, of the draining cannula, the draining tube is longer than the draining cannula, different types of draining tubes are arranged, the parts which are 3 centimeters from the head ends of the draining tubes are processed into 90 degrees of an arc or 135 degrees of an arc, a stylet is 0.3 centimeter longer than the outer cannula, and a spiral tip is arranged on the stylet. The multi-functional intracranial hematoma puncture draining trocar is favorable to smooth insertion, and infusion, flushing and draining can be simultaneously carried out. The multi-functional intracranial hematoma puncture draining trocar has the most important characteristics that when hematoma is too big or a puncture needle does not reach a hematoma center, through the adjustment of the direction and the depth of the draining cannula and the draining tube, the draining tubes with different degrees of an arc are adopted according to conditions so as to reach any hematoma part and fully drain or suck away the hematoma. The defect that the existing other intracranial hematoma puncture needles require repeated puncture is overcome. The multi-functional intracranial hematoma puncture draining trocar can be widely used for the minimally invasive puncture draining of intracranial hematoma or hydrocephalus.

Description

A kind of multi-functional intracranial hematoma puncture drainage sleeve bobbin

Technical field

This utility model relates to a kind of multi-functional intracranial hematoma puncture drainage sleeve bobbin, belongs to technical field of medical instruments.

Background technology

Existing intracranial puncture surgical drainage, lack special-purpose puncture drainage tube, for realizing the apparatus that puncture drainage is conventional, it is metal type brain pin, it can only be determined a position and can not change, if hematoma is excessive or operation is accurate to hematoma center not, drainage effect is not good, need to again locate, puncture drainage, cause patient to damage increasing, the prior art drawback is: can not, by adjusting the direction of drainage tube and any position drain that the degree of depth arrives hematoma, may cause drainage effect not good, again puncture drainage, strengthen patient's damage, increase its financial burden.

Summary of the invention

For the above-mentioned defect existing in prior art, this utility model aims to provide a kind of rational in infrastructure simple, easy for operation, drain accurate positioning, drain is unimpeded and thoroughly purify the blood, can synchronously pour into, rinse, drain, can be by adjusting direction and the degree of depth of drainage casing tube and drainage tube when in hematoma, excessive or puncture needle does not reach hematoma center, adopt the drainage tube of different radians and arrive any position of hematoma, abundant drain hematoma or drawing hematoma, having solved existing other puncture needle for intractanial hematoma needs the shortcoming of repeated localised puncture, can be widely used in intracranial hematoma or hydrocephalic microtrauma puncture drain, it is a kind of multi-functional intracranial hematoma puncture drainage sleeve bobbin of safe and reliable solution intracranial hematoma.

A kind of multi-functional intracranial hematoma puncture drainage sleeve bobbin that this utility model adopts, comprise trocar sheath, nook closing member, drainage casing tube, drainage tube, described drainage casing tube is threeway needle body, threeway needle body is provided with side draining hole, drainage casing tube outer wall is provided with length groove sign and direction groove sign, and drainage casing tube front end is closed, and 90 degree radian ends are provided with flow-guiding mouth, described drainage tube outer wall is provided with length groove sign and direction groove sign, matches to identify direction with drainage casing tube groove sign.

This utility model is achieved through the following technical solutions:

Described drainage tube Length Ratio drainage sleeve pipe range 3-4 centimetre, and make in head end 2-3 centimeters the dissimilar drainage tube that 90 degree, 135 are spent radians.

Described drainage tube rear end is provided with drainage tube handle.

The supporting block in described drainage casing tube threeway needle body top.

Trocar sheath can be enclosed within outside drainage casing tube and nook closing member, and nook closing member Length Ratio overcoat pipe range 0.1-0.3 centimetre, is helical-tip.

This utility model compared with prior art, realized at trocar sheath and nook closing member and having penetrated after skull and cerebral dura mater, drainage casing tube is conducive to smooth insertion by trocar sheath, can synchronously pour into, rinse, drain, by adjusting direction and the degree of depth of drainage casing tube and drainage tube, according to patient's different differences, adopt the drainage tube of different radians and arrive any position of hematoma, drain positional accuracy is high, abundant drain hematoma or drawing hematoma, having overcome existing other puncture needle for intractanial hematoma needs the shortcoming of repeated localised puncture, especially reduced the damage of patient's cerebral tissue and nerve fiber, thereby reach rapid, effective and painless therapeutical effect, patient all can reach desirable therapeutic effect.

The specific embodiment

As shown in Figure 1 and Figure 2, drainage casing tube 1 is threeway needle body, threeway needle body is provided with side draining hole 2, drainage casing tube 1 outer wall is provided with length groove sign 3 and direction groove sign 5, drainage casing tube 1 front end is closed, be 90 degree radians, end is provided with flow-guiding mouth 4, the described drainage casing tube 1 threeway needle body top block 6 supporting with it.

As shown in Figure 3, Figure 4, described drainage tube 7 outer walls are provided with length groove sign 8 and direction groove sign 10, match to identify direction with drainage casing tube 1 groove sign; The long 3-4 centimetre of drainage tube 7 Length Ratio drainage casing tube 1, and be moulded radian in drainage tube 7 head end 2-3 centimeters, described drainage tube 7 head end radians may be formed into 90 degree, 135 degree, and described drainage tube 7 rear ends are provided with drainage tube handle 9, and end is easy to connect syringe or drainage bag.

As shown in Figure 5, Figure 7, by electric drill, nook closing member 12 and trocar sheath 11 is fixing after through skull and cerebral dura mater, extract nook closing member 12, drainage casing tube 1 is inserted to trocar sheath 11, it is gently pushed into hematoma center, rear end is connected with syringe, now can synchronously pour into, flushing, drawing hematoma, or the block supporting with it 6 of screwing on drainage casing tube 1 threeway needle body top, one of drainage bag is connected with threeway needle body side draining hole 2, now can continue to carry out hematoma drain.

As shown in Figure 6, while using this multi-functional intracranial hematoma puncture drainage sleeve bobbin, according to direction and the degree of depth of hematoma position rotation drainage casing tube 1 and drainage tube 7, select to be applicable to the drainage tube 7 of radian, and make the radian direction of drainage tube 7 aim at hematoma center, release drainage tube, to hematoma center, connect syringe, drawing hematoma, or connect drainage bag drain hematoma cause clean till.
