FIG. 1 is a schematic cross-sectional view of a biopsy aspirator of the present application.
Fig. 2 is a schematic structural view of the puncture biopsy aspirator of the present application.
Detailed Description
Referring to fig. 1, the puncture biopsy aspirator of the present application comprises an outer sleeve 1, a puncture tube 2, a biopsy sealing pot 3 and a puncture tube control mechanism.
The front end of the puncture tube 2 is inserted into the outer sleeve 1, the tail end of the puncture tube is connected with the biopsy sealing tank 3, and the biopsy sealing tank 3 is connected with a negative pressure source. In this embodiment, the puncture tube 2 is a hollow puncture needle, which not only can play a role in puncturing focal tissues, but also can directly extract focal tissues into the biopsy sealing tank through the hollow puncture needle by being connected with a negative pressure source, so as to ensure that a biopsy sample is not polluted by external environment, and the detection result is accurate and reliable. It should be noted that the "front end" referred to in the present application means an end to be inserted into the body, and the "end" means an end to be left outside the body.
In this embodiment, the puncture tube control mechanism includes a slot 4 disposed on a sidewall of the distal end of the outer sleeve 1 and a push rod 5 disposed on the puncture tube 2, where the push rod 5 moves along the slot 4 to drive the front end of the puncture tube 2 to extend or retract from the front end of the outer sleeve 1. In a more preferred embodiment, the clamping groove 4 is an L-shaped clamping groove, and two ends of the L-shaped clamping groove are respectively fixed ends for enabling the front end of the puncture tube 2 to be in an extending or retracting state. The puncture tube control mechanism drives the puncture tube 2 to axially move along the outer sleeve 1 by pushing the push rod 5 to move in the clamping groove 4, and the front end of the puncture tube extends out of or retracts back to the front end of the outer sleeve 1, so that when the puncture biopsy aspirator enters a body, the front end of the puncture tube returns to the outer sleeve, thereby not only achieving the purpose of protecting the puncture tube, but also avoiding damaging other tissues.
In order to reduce the influence of the secretion in the body, a first side hole 6 is formed in the side wall of the outer sleeve 1, a first bifurcation of a bifurcation 7 is connected to the first side hole 6, a second bifurcation and a third bifurcation of the bifurcation 7 are respectively used for connecting a flusher and a negative pressure source, and a flushing valve 8 and an attracting valve 9 are respectively arranged on the second bifurcation and the third bifurcation. And a sealing ring 10 is arranged between the inner wall of the outer sleeve 1 and the outer wall of the puncture tube 2, and the clamping groove 4 and the first side hole 6 are respectively positioned at two sides of the sealing ring 10. Thus, the flushing valve 8 is opened, the flushing device can enter the body through the channel between the outer sleeve 1 and the puncture tube 2 for flushing, then the suction valve 9 is opened, and under the action of the negative pressure source, the secretion or flushing water in the body can be sucked out of the body through the channel between the outer sleeve 1 and the puncture tube 2.
In this embodiment, the biopsy sealing tank 3 is provided with a receiving tube 11 and a negative pressure tube 12, one end of the receiving tube 11 is connected with the tail end of the puncture tube 2, and the other end extends into the biopsy sealing tank 3 and is close to the tank bottom; one end of the negative pressure tube 12 is used for connecting with a negative pressure source, and the other end extends into the biopsy sealing tank 3 and is close to the tank top. Since the negative pressure tube 12 is connected to a negative pressure source, when the negative pressure source is turned on, the negative pressure source causes negative pressure to be formed in the sealed biopsy canister 3, so that the lesion tissue is sucked into the sealed biopsy canister 3 through the puncture tube 2.
Furthermore, in this embodiment, a second side hole 13 is formed in the third bifurcation between the suction valve 9 and the negative pressure source port, the second side hole 13 is connected to the negative pressure tube 12, and a sampling valve 14 is disposed on the negative pressure tube 12, so that the suction of the secretion in vivo and the extraction of the biopsy sample adopt the same negative pressure source port and are controlled by different valves.
Referring to fig. 2, the puncture biopsy aspirator of the present application comprises a handle 15 connected with the outer sleeve 1, the Y-pipe 7 and a part of the negative pressure pipe 12 are positioned inside the handle 15, the handle 15 comprises a flushing button 16, a suction button 17 and a sampling button 18, and the flushing button 16, the suction button 17 and the sampling button 18 respectively correspond to the flushing valve 8, the suction valve 9 and the sampling valve 14 and are used for controlling the opening and closing of the flushing valve, the suction valve 9 and the sampling valve 14. The puncture biopsy aspirator has reasonable design, can realize multiple works of flushing, sucking, puncturing and extracting biopsy samples by only pressing the corresponding key and pushing the push rod by one hand during operation, and has simple operation, convenient use and reliable result.
The above description is only of the preferred embodiments of the present application, and is not intended to limit the application in any way, and some simple modifications, equivalent variations or modifications can be made by those skilled in the art using the teachings disclosed herein, which fall within the scope of the present application.
