Problems solved by technology

Most of the sealing structures of multi-channel single-hole endoscopic trocars currently on the market are relatively complicated or cumbersome in operation, and most of the sealing structures are made of plastic and silica gel to achieve the purpose of sealing, but in this case, due to the nature of the plastic hard, which will inevitably affect the overall softness of the product during operation, and also have a certain impact on the range of motion of the device; in addition, there are fewer types of multi-channel single-hole endoscopic trocars currently on the market, and they are relatively single , except for the removable channel tube (incision protective sleeve), other structures of the product are integrated, and the porous operating platform cannot be rotated according to the actual operation needs, so it is inevitable that: during the operation, if the doctor thinks according to the actual needs When operating at a different angle or adjusting the field of view, the doctor must rely on the doctor to adjust the body angle to meet the requirements, which causes great inconvenience to the operation

Embodiment 1

[0022] Such as Figure 1-3 Shown: a multi-channel single-hole endoscopic trocar, which includes a multi-hole operating platform 1 and a channel tube 2 connected to the multi-hole operating platform 1. The channel tube 2 includes a tubular flexible film channel 3 and a flexible film channel located on the flexible film channel. 3, the lower ring 4 at the lower end, the upper end of the flexible film channel 3 is connected to the porous operating platform 1, and the porous operating platform 1 is connected to the flexible film channel 3 through a sealing connection assembly, and the sealing connection assembly includes a flexible The flexible flange 5 at the upper end of the membrane passage 3, the disk surface of the flexible flange 5 is connected to the lower surface of the porous operating platform 1, and the flexible flange 5 connects the porous operating platform 1 with the flexible membrane passage 3 and makes the porous operation Platform 1 rotates on its central axis. T...

Embodiment 2

[0048] Embodiment 2 of the present invention has substantially the same structure as Embodiment 1, and the main difference is that in Embodiment 2, the ring-shaped sealing plate A9 in Embodiment 1 is replaced by the ring-shaped sealing plate B12.

[0049] In the second embodiment, the sealing connection assembly includes an annular sealing plate B12 arranged between the surface of the flexible flange 5 and the lower surface of the porous operating platform 1, and the lower surface of the annular sealing plate B12 is connected to the flexible flange. 5 is fixedly connected to the disk surface, the upper surface of the annular sealing plate B12 is provided with an annular groove C13 and / or an annular protrusion C, and the lower surface of the porous operating platform 1 is provided with an interference fit with the annular groove C13 The annular protrusion D14 and / or the annular groove D that interferes with the annular protrusion C.

[0050] Such as Figure 4 , 5 Shown: In th...

Embodiment 3

[0051] Embodiment 3: Embodiment 3 of the present invention has substantially the same structure as Embodiments 1 and 2. The main difference is that the ring-shaped sealing plate B and the ring-shaped sealing plate A are not provided in Embodiment 3, but the porous operating platform 1 The lower surface of the lower surface is in direct contact with the upper surface of the flexible flange 5. In Embodiment 3: the lower surface of the porous operating platform 1 is provided with an annular protrusion E and / or an annular groove E, and the flexible flange An annular groove F matching the annular protrusion E and / or an annular protrusion F matching the annular groove E are provided on the upper surface of the disk 5 .

[0052] Because when the porous operating platform 1 and the flexible flange 5 are both made of flexible materials, they are in direct contact, the friction of the contact surface will be relatively larger than that of the first and second embodiments, and the sealing...

Abstract

The invention relates to a novel multichannel one-hole endoscope puncture outfit. The novel multichannel one-hole endoscope puncture outfit comprises a multi-hole operation platform and a channel pipe connected with the multi-hole operation platform. The channel pipe comprises a tubular flexible film channel and a lower ring arranged at the lower end of the flexible film channel, the upper end of the flexible film channel is connected with the multi-hole operation platform, and the multi-hole operation platform and the flexible film channel are connected through a sealing connection assembly. The sealing connection assembly comprises a flexible flange plate arranged at the upper end of the flexible film channel in a sleeving mode. The plate face of the flexible flange plate is connected with the lower surface of the multi-hole operation platform, the multi-hole operation platform is connected with the flexible film channel through the flexible flange plate, and the multi-hole operation platform rotates with the flexible flange plate as a center axis. The novel multichannel one-hole endoscope puncture outfit is simple in structure and convenient to operate, and when a doctor needs to change an angle to carry out operation in the actual operation process, operation angle regulation can be completed only by rotating the multi-hole operation platform.

Description

technical field [0001] The invention relates to a multi-channel single-hole laparoscopic trocar. Background technique [0002] With the development of medical technology, minimally invasive surgery using laparoscopic technology has been increasingly popularized and used in China. In laparoscopic surgery, 2-4 hole operations are often used, one of which is opened on the navel (or other parts of the abdomen) of the human body to avoid leaving long strips of scars on the patient's abdominal cavity. After recovery, only in the abdominal cavity There are 1-3 linear scars of 0.5-1 cm left on the site, which can be said to be a small wound and less painful surgery, so some people call it "keyhole" surgery. The development of laparoscopic surgery reduces the pain of surgery for patients, shortens the length of the patient's neck, and relatively reduces the expenditure of patients. It is a surgical project that has developed rapidly in recent years. [0003] Minimally invasive lapa...
