Detachable converter for pleuroperitoneal cavity mirror operation

Technical Field

The utility model relates to the technology of medical surgical instruments, in particular to a detachable converter for the pleuroperitoneal cavity mirror operation.

Background

Puncture is a diagnosis and treatment technology for puncturing a puncture needle into a body cavity to extract secretion for testing, or injecting gas or contrast agent into the body cavity to perform contrast examination, or injecting medicine into the body cavity. It is widely used because of its low trauma, low complications and low pain. The small incision of the thoraco-laparoscopic surgery is used for placing a cannula inserted into a thoraco-laparoscopic surgery and surgical instruments, the puncture of the small incision is only 0.2-1.5 cm generally, and only individual surgery needs to be expanded properly due to the use of special surgical instruments or difficulty in taking specimens. In the operation process, stab and adopt the puncture outfit to establish after the mouth has opened and fix after the apparatus passageway, the doctor needs the instrument of transform difference, like speculum, sampling forceps, separation pincers, gas tube etc. adopt the converter of bushing structure among the prior art mostly, need the whole part of dismouting during the change, change time many, troublesome poeration, minute second all can bring the discomfort for the patient. Temporary fixation is also known in the art, such as patent publication No. CN208799254U, a laparoscopic converter comprising an open-close base and a reversible joint; the opening-closing type base comprises an adjustable bayonet and a connecting rod, the connecting rod is vertically fixed on the adjustable bayonet, and one side of the turnable joint is hinged at the upper end of the connecting rod; the adjustable bayonet comprises two arc-shaped clamping blocks, a shell and an adjusting handle, the rear ends of the arc-shaped clamping blocks are hinged together, the adjusting handle is installed on the shell, and the arc-shaped clamping blocks are installed in the shell; the lower end of the adjusting handle is connected with the arc-shaped clamping block. The split type base in the device is provided with two adjustable bayonets which are screwed and loosened through the adjusting handle, so that not only are the parts manufactured complicated and the assembly difficult, but also the parts are easy to be screwed and loosened easily during use, or the instrument cannot be fixed due to the fact that the parts are not screwed in the hand, and especially air leakage is easy to cause in the inflating process.

SUMMERY OF THE UTILITY MODEL

In the detachable converter for a pleuroperitoneal laparoscopic surgery, the catheter body preferably passes through the base plate vertically.

In the detachable converter for a pleuroperitoneal laparoscopic surgery, preferably, an inner hole at the inlet end of the catheter body is a taper hole.

This technical scheme uses the puncture ware as the reference body, cooperates puncture ware mouth of pipe structure, designs one and directly clamps the fixed knot of installing the puncture ware mouth of pipe, and this fixed knot articulates an organic whole with a base plate again, wears to be equipped with the pipe body in the base plate, and the diameter of pipe body is special, fixes knot promptly and cooperates with conventional puncture ware mouth of pipe, and the instrument poling of a diameter specification is complied with to puncture ware internal diameter itself, and pipe body internal diameter is less than the puncture ware internal diameter, satisfies the instrument poling of another kind of diameter specification. Because still need aerify sometimes and carry out the expansion of sampling area inner chamber at the in-process of diagnosing, and instrument poling basically uses stainless steel pipe or plastics rubber sleeve, in order to avoid gas leakage, is equipped with the seal cover at the entry end cover of pipe body, and this seal cover adopts soft elastic silica gel to make, and the hole is less than instrument poling, and when instrument poling passed through the seal cover, both will closely combine to make instrument poling obtain sealedly. The fixing buckle is in a snap ring structure form with an opening, the base plate is hinged with the swing rod, and the length of the swing rod ensures that the catheter body is completely positioned on the same central line of the puncture tube when the snap ring is matched with the puncture tube.

Furthermore, the outer diameter of the outlet end of the catheter body is conical, so that the catheter body is easy to guide and compress when being matched with the tube opening of the puncture outfit. The snap ring is the arc elastomer that exceeds a semicircle, is made by the stainless steel billet, and self just has fairly good elasticity, and this semicircle actually exceeds semicircle 1-2mm, just can fix completely when withholding the puncture ware pipe, and it is relatively easy again during the dismantlement, in order to guarantee the sufficient structural strength of this device and life, choose the stainless steel billet of the great thickness of stability height for use to set up along the heavy groove strip of axial arrangement on the snap ring surface and lack, make the snap ring use stable, the operation is light.

The utility model has the advantages that: the puncture outfit converter is simple to operate, fast in positioning, strong in stability and high in sealing performance, operation efficiency is greatly improved, labor intensity of medical staff is relieved, operation time is shortened by capturing seconds, and operation accidents are avoided.
