Description

Disposable vertebral capsule cervical dilator

technical field

The utility model relates to the technical field of cervical dilation, in particular to a disposable vertebral capsule type cervical dilator.

Background technique

Cervical dilators are commonly used instruments in gynecological surgery. Currently, the cervical dilators used clinically are metal dilating rods, which are divided into different sizes to dilate the uterus sequentially. The chance of nosocomial infection will also increase. In particular, hysteroscopic surgery is popular. Before hysteroscopic surgery, it is required to dilate the cervix by about 10-10.5mm. If the dilation of the cervix fails, the hysteroscopic surgery cannot be successfully completed. Therefore, there is an urgent need for a cervical dilator that continuously dilates the cervix once and can relieve the patient's pain.

In the existing clinical technology, Chinese patent CN2012202519743 discloses a balloon cervical dilator, which is mainly composed of an inflatable balloon and an inflatable tube connected thereto. A plug is connected, the expansion air bag is double-layered, the inner expansion air bag is located in the outer expansion air bag, and the inflation tube communicates with the inner expansion air bag. By injecting a certain amount of normal saline into the inflatable tube, the inflation balloon is slowly stretched, so that the cervix expands. Since the inflation balloon is double-layered, the thickness of the balloon is reinforced, and it should not be broken by surgical forceps during use. There are the following defects: 1. During the operation, it is necessary to send the dilator inflation balloon to the cervix through hard instruments such as vaginal dilator and surgical forceps, which is very prone to damage to tissues such as the cavity mucosa; 2. To expand the inflation balloon by injecting water Finally, the plug needs to be unscrewed to allow the water in the capsule to drain freely, so that there is residual water in the capsule. When the cervical dilator is pulled out, the residual water in the capsule will continue to wade out, causing inconvenience; especially when the operation is not Be careful not to shrink the inflation balloon to an appropriate expansion capacity by pumping water when the inflation balloon is too large; third, there is no mark reference on the inflation tube, which makes it difficult for the doctor to confirm the pressure in the inflation balloon; fourth, the inflation after expansion The airbag is stretched in a circular shape, and the stretching process aggravates the patient's pain.

Contents of the invention

The utility model overcomes the deficiencies in the prior art, and provides a one-time vertebral capsule type cervical dilator, which can complete the expansion process at one time, and the expansion is soft, preventing the occurrence of pain and cervical tearing, and at the same time, it can be used during cervical dilation. Simultaneously perform negative pressure suction to aspirate secretions.

The purpose of this utility model is achieved through the following technical solutions.

Disposable vertebral capsule type cervical dilator, including extending the main channel tube deeply, the drainage end of the extending main channel tube is provided with a suction hole, and the extending main channel tube includes water injection and air injection channel, local anesthetic drug channel, Straight operation channel, the top of the water injection and gas injection channel is provided with a water injection and gas injection sealing bag injection outlet, the bottom of the water injection and gas injection channel is connected to the water injection and gas injection inlet, and the water injection and gas injection sealing bag injection outlet is peripherally installed There is a water injection air injection sealing bag, the width of the top of the water injection air injection sealing bag is smaller than the width of the bottom, and the width of the water injection air injection sealing bag gradually increases from the top to the bottom, and the top of the local anesthetic channel is set There is a front-end outlet of the local anesthetic, the front-end outlet of the local anesthetic is located between the suction hole and the top of the water injection air injection sealing bag, the bottom of the local anesthetic passage is provided with a local anesthetic inlet, and the straight The operating channel is inserted with a central support straight catheter core.
