Description

Cerebral hemorrhage hematoma channel establishing device

Technical Field

The invention relates to the field of surgical instruments, in particular to a cerebral hemorrhage hematoma channel establishing device.

Background

Along with the development of endoscope technology, the endoscope is widely applied to surgical treatment, particularly has good development on cerebral hemorrhage treatment, and is diversified;

The existing treatment mode of the cerebral hemorrhage hematoma is to suck the hematoma by virtue of a puncture needle and a drainage tube and then carry out the next treatment, however, the position of the hematoma needs to be monitored constantly in the operation process, and other operation treatments need to be carried out by combining the position, so that a channel needs to be established for the hematoma position, and no related equipment can meet the requirements at present.

In view of the problems in the prior art, the invention designs and manufactures a cerebral hemorrhage hematoma channel establishing device by combining years of design and use experience of related fields and assisting with over-strong professional knowledge, so as to overcome the defects.

Disclosure of Invention

For the problems in the prior art, the cerebral hemorrhage hematoma channel establishing device provided by the invention can establish a channel with the outside of the skull at the hematoma position, and improve the operation efficiency and success rate.

In order to achieve the purpose, the technical scheme adopted by the invention is as follows: a cerebral hemorrhage hematoma channel establishing device comprises a drainage tube, wherein a puncture needle is inserted into the drainage tube, and the rear end of the drainage tube can be connected with an injector;

after the drainage tube is pulled out of the puncture needle, the puncture needle can be sleeved with a sleeve combination and guided to extend into the hematoma;

The sleeve assembly comprises a sleeve and a cylinder core arranged in the sleeve, and a channel is arranged in the center of the cylinder core and can be used for the puncture needle to penetrate through;

the cylinder core can be fixedly connected with the puncture needle, and the cylinder core and the puncture needle can be separated from the sleeve.

Preferably, the drainage tube is provided with scales.

Preferably, when the injector is connected with the drainage tube, the puncture needle is pulled out of the drainage tube.

Preferably, the rear end of the sleeve is provided with a fixing paste, and the fixing paste can be pasted with the head.

Preferably, the tail end of the channel is provided with a thread and an expansion bolt, a through hole is formed in the center of the expansion bolt, and the through hole is gradually reduced after the expansion bolt is screwed into the thread and can clamp the puncture needle.

Preferably, the barrel core head is provided with a conical structure.

The invention has the advantages that:

1. the invention firstly utilizes the puncture needle and the drainage tube to reach the hematoma position, then draws out the puncture needle, sucks out the hematoma by means of the drainage tube and the injector, then guides the sleeve and the cylinder core into the cranial cavity by means of the guide of the puncture needle, and finally takes out the puncture needle and the cylinder core, and reserves the channel established by the sleeve.

2. The sleeve combination structure comprises the sleeve and the barrel core which can be separated from the sleeve, and the barrel core ensures that the sleeve combination can extend into a cranial cavity, so that the risk of the sleeve on the operation due to poor guidance quality of the sleeve is prevented.

3. According to the invention, through the structure of the thread at the tail end of the channel in the barrel core and the expansion bolt, the puncture needle and the barrel core are ensured to be taken out simultaneously, and the operation risk is further reduced.

Detailed Description

In order to facilitate understanding for those skilled in the art, the present invention will be further described with reference to the accompanying drawings.

As shown in fig. 1 to 5, a cerebral hemorrhage hematoma channel establishing device comprises a drainage tube 1, scales are arranged on the drainage tube 1, a puncture needle 2 is inserted into the drainage tube 1, the rear end of the drainage tube 1 can be connected with an injector 3, and when the puncture needle 2 is pulled out of the drainage tube 1, the injector 3 can be connected with the drainage tube 1;

After the drainage tube 1 is pulled out from the puncture needle 2, the puncture needle 2 can be sleeved with a sleeve combination and guided to extend into a hematoma 8; the sleeve combination comprises a sleeve 5 and a cylinder core 4 arranged in the sleeve 5, the head of the cylinder core 4 is designed into a conical structure so as to be convenient to enter a cranial cavity, and a channel is arranged in the center of the cylinder core 4 and can be used for penetrating the puncture needle 2; the tail end of the channel is provided with a thread and an expansion bolt 7, the center of the expansion bolt 7 is provided with a through hole, the through hole is gradually reduced after the expansion bolt 7 is screwed into the thread and can clamp the puncture needle 2, the barrel core 4 is fixedly connected with the puncture needle 2 through the tail end of the channel, and the barrel core 4 and the puncture needle 2 can be separated from the sleeve 5 together.

According to the invention, through the structure of the thread at the tail end of the channel in the barrel core 4 and the expansion bolt 7, the puncture needle 2 and the barrel core 4 can be ensured to be taken out simultaneously, the injury risk of the process operation on the cranial cavity is reduced, and the sleeve combined structure comprises the sleeve 5 and the barrel core 4 which can be separated from the sleeve 5, so that the sleeve combination can be ensured to extend into the cranial cavity by means of the barrel core 4, and the risk of the sleeve 5 caused by poor guiding property and the operation is prevented.
