Description

Technical Field

[0001] The present invention belongs to the field of surgical diagnostic devices, and particularly relates to an endoscopic puncture assembly and system. Background Art

[0002] An endoscope is an instrument used for medical diagnosis and treatment. It can be inserted into the human body through natural cavities or artificial incisions to observe and operate on various organs and tissues. An endoscope usually needs to be used in conjunction with a trocar. The trocar establishes a channel through a sheath. The sheath is used to protect the endoscope, provide a channel, and convey gases, liquids, optical fibers, electrodes, etc. The fixation between the endoscope and the sheath is an important technical problem because it directly affects the operating stability, safety, and efficiency of the endoscope.

[0003] A trocar is an instrument used for performing puncture operations, usually consisting of a three-way connector, a luer connector, and a puncture needle. The three-way connector is a device for connecting the puncture needle and a syringe, capable of adjusting the flow direction of the liquid and observing the properties of the liquid; the luer connector is a device for connecting the three-way connector and the sheath, capable of adjusting the connection angle and position, and increasing the firmness and tightness of the connection; the puncture needle is a needle-shaped instrument used for performing puncture operations, having a sharp front end capable of penetrating the wall layer of the human body or an industrial pipeline.

[0004] Currently, the endoscope and the sheath are installed through an interference fit. The fixing method is not flexible enough and cannot be adjusted according to different puncture directions and requirements, affecting the accuracy and effectiveness of the puncture; when the endoscope and the trocar are connected by threads, loosening or detachment easily occurs when rotating in one direction, affecting the stability and safety of the puncture; in summary, the design of the existing endoscopic trocar cannot meet the requirements of high efficiency, safety, and convenience of endoscopic puncture.

[0005] Therefore, it is necessary to develop an endoscopic puncture assembly and its system to solve the technical problem of fixing the endoscope, puncture needle, and sheath. Summary of the Invention

[0006] The purpose of the present invention is to provide an endoscopic puncture assembly and system to solve the problem of difficult fixation of the endoscope, puncture needle, and sheath.

[0007] To solve the above technical problems, the present invention is realized through the following technical solutions:

[0008] In a first aspect, an endoscopic puncture assembly is provided, characterized in that the assembly includes;

[0009] A channel assembly, which is tubular and used for receiving an endoscope and a puncture assembly;

[0010] A puncture assembly, having a pressure concentration point at the distal end and a pressing portion at the proximal end;

[0011] The tube sleeve assembly is provided with a through hole for receiving the endoscope and the puncture assembly, and the proximal end of the channel assembly is fixedly mounted on the distal end of the through hole;

[0012] The adjusting component is annular and is movably mounted at the distal end of the tube sleeve component in a rotatable manner. The proximal end is provided with a mounting slot / boss fixedly connected to the pressing portion and / or the endoscope handle.

[0013] On the other hand, an endoscope puncture system is provided, the system comprising an endoscope puncture assembly and an endoscope; the endoscope comprises a mounting slot which is mounted and fixed to the adjustment assembly.

[0014] Beneficial effects:

[0015] The utility model realizes the rapid installation and removal of the endoscope and the puncture component by adjusting the component rotation to fit the card slot, avoids the shortcomings of interference fit and threaded connection, and improves the convenience and efficiency of operation.

[0016] The utility model realizes the close matching and free rotation of the endoscope and the adjustment component by means of the endoscope mounting boss and the giving way slot, thereby increasing the field of view and flexibility of the endoscope.

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0029] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "periphery", etc. indicating the orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the component or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of the present invention.

[0030] Among them, the same reference numerals in each of several views refer to the same or corresponding elements. As used herein, the term "far" refers to the direction in which a part of the endoscope, access component or its component is farther from the operator (such as a doctor). For example, "distal direction" is the direction in which the endoscope is inserted, and "distal end" is one end in the insertion direction of the endoscope; while the term "proximal" refers to the direction in which a part of the endoscope, access component or its component is closer to the operator. For example, "proximal direction" is the direction in which the endoscope is withdrawn, and "proximal end" is one end in the withdrawal direction of the endoscope.

[0031] According to the present disclosure, during a surgical operation, by adjusting the rotation and cooperation of the card slots of the component, the rapid installation and disassembly of the endoscope and the puncture component are realized, avoiding the deficiencies of interference fit and threaded connection, and improving the convenience and efficiency of the operation.
