Device for excising and sucking tissue from human body

Abstract

The invention provides a device for excising and sucking tissue from a human body. The device comprises an insertion structure, a vibration handle with an inner pipe and a high-frequency vibration source, a negative pressure device and an electronic control device; the insertion structure comprises a main body portion and an excising portion which are both in a single-layer pipeline shape, the front end of the main body portion is connected with the excising portion, the back end of the main body portion is connected with the vibration handle, and the front end of the inner pipe is communicated with an inner cavity of the insertion structure; the negative pressure device comprises a negative pressure pipe, a vacuum pump and a liquid storage container, the back end of the inner pipe is connected with the negative pressure pipe, the negative pressure pipe is connected with the vacuum pump, and the vacuum pump is connected with the liquid storage container through a pipeline; the electronic control device is electrically connected with the high-frequency vibration source and the vacuum pump; a suction hole is formed in the surface of the excising portion and communicated with the inner cavity of the insertion structure; a plurality of excising wires are arranged in the suction hole and excise the human body tissue along with vibration of the high-frequency vibration source when the high-frequency vibration source drives the excising portion to vibrate at high frequency, the negative pressure device works to suck the human body tissue into the suction hole, and then the human body tissue enters the liquid storage container along the inner cavity. The human body tissue can be continuously and efficiently smashed and removed, and the operation effect is improved.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a device for cutting and sucking tissue from a human body. Background technique [0002] In the medical industry, today’s human tissue cutting is generally done with a scalpel cutting operation, but this method has a large trauma, the patient is more painful, and it is easy to leave scars, etc., and the organs on the human body are more delicate. Also difficult to adopt the mode of scalpel cutting to finish. For example, micro-scissors or bite cutters are commonly used for laparoscopic tissue resection, but the amount of tissue removed is very limited. Another example is to cut the vitreous body of the eye tissue by using a vitreous body cutter to cut and absorb the vitreous body. Since the vitreous body in the eye is viscous, in order to achieve this viscous vitreous body, machine The film and blood clots are gradually crushed and removed. The existing vitreous cutter has a re...

[0002] In the medical industry, today’s human tissue cutting is generally done with a scalpel cutting operation, but this method has a large trauma, the patient is more painful, and it is easy to leave scars, etc., and the organs on the human body are more delicate. It is also not easy to use a scalpel to cut

For example, micro-scissors or bite cutters are commonly used for laparoscopic tissue resection, but the amount of tissue removed is very limited

Another example is to cut the vitreous body of the eye tissue by using a vitreous body cutter to cut and absorb the vitreous body. Since the vitreous body in the eye is viscous, in order to achieve this viscous vitreous body, machine The film and blood clots are gradually crushed and removed. The existing vitreous cutter has a relatively complicated structure design. It is generally a double-layered pipeline with a high degree of cooperation. When working, the inner tube reciprocates at high speed. The vitrified cutter with this structure It is not only large in size, but also inconvenient to operate, low in efficiency, difficult to further miniaturize, and unable to deal with hard diseased tissues (such as lens nucleus). Poor cutting and suction

At the same time, because the liquid flow is intermittent, it will cause the tissues in the eye to shake greatly, which may easily lead to retinal tear or accidental injury.
