Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

As shown in fig. 1, a filtering type laparoscopic puncture device includes: a sleeve seat 1, a sleeve 2 and a filter assembly 3. The middle of the sleeve seat 1 is a hollow seat body, the side wall of the sleeve seat 1 is communicated with an air outlet pipe 4, and a control switch for controlling the air outlet pipe 4 to be opened and closed can be arranged on the air outlet pipe 4; the sleeve 2 is connected to one end of the sleeve seat 1, and the sleeve 2 is communicated with the hollow area of the inner cavity of the sleeve seat 1; wherein, sleeve seat 1 connects into an integral whole with sleeve 2, and filter component 3 installs in sleeve seat 1's inner chamber center for the gaseous filtration of deriving in sleeve 2, and the gaseous discharge of following the filtration in outlet duct 4.

The structure of the cannula holder 1 and the cannula 2 is the same as that of the existing disposable abdominal cavity puncture outfit in the market, the air tightness can be well guaranteed, and only the arrangement of a plurality of filter components in the cannula holder 1 is adopted.

The device allows most inhalable particulate matters and harmful gases to be filtered through the filter assembly, and then the inhalable particulate matters and the harmful gases are discharged to the outside air, so that the damage of exhaust emission to related staff is reduced.

In use, the cannula 2 is inserted into the abdominal cavity of a patient, when smoke is generated during surgery, the control switch in the air outlet pipe 4 is turned on, and the abdominal cavity is in a relatively high pressure state because the abdominal cavity is filled with carbon dioxide gas in advance, after the control switch is turned on, the gas in the abdominal cavity can enter the cannula holder 1 along the cannula 2, the smoke entering the cannula holder 1 is absorbed by the filter assembly 3 to pass through, and then is discharged to the external environment through the air outlet pipe 4, wherein the filter assembly 3 mainly adopts a physical treatment mode to perform gas purification.

Specifically, as shown in fig. 1-2, the filter assembly 3 includes an adsorption layer 31 and a filter layer 32, the adsorption layer 31 wraps the filter layer 32 in its inner cavity, and the air outlet end of the air outlet pipe 4 is located above the adsorption layer 31, and a cylindrical hole 33 is formed in the center of the inner cavity of the adsorption layer 31 along its height direction.

Wherein the adsorption layer 31 is made of melt blown cloth, and the filter layer 32 is made of one or more materials of active carbon or soda lime.

The activated carbon or the sodium lime is wrapped by the melt-blown cloth to form a columnar-like structure which is attached to the side wall of the inner cavity of the sleeve seat 1, and the gas entering the sleeve seat 1 sequentially passes through the melt-blown cloth, the activated carbon and the melt-blown cloth, wherein the melt-blown cloth mainly fixes the activated carbon or the sodium lime, so that the whole filter assembly 3 is conveniently placed, and the columnar holes 33 are conveniently arranged, so that the insertion of an external surgical instrument is facilitated.

Because the side wall of the cylindrical hole 33 mainly comprises the melt-blown cloth, the melt-blown cloth has stronger toughness, and the aperture of the cylindrical hole 33 is easy to change relatively, when an external surgical instrument is inserted, a larger gap is easy to generate between the cylindrical hole 33 and the external surgical instrument, the gap at an angle is easy to cause gas leakage, namely part of gas is discharged from the gap without being purified by the filter assembly 3, and the uncleaned gas can cause harm to medical staff or patients after being discharged, so as to avoid the phenomenon.

Specifically, as shown in fig. 1, the inner cavity of the cylindrical hole 33 is provided with a catheter 5, the peripheral side of the catheter 5 is attached to the side wall of the adsorption layer 31, the catheter 5 has a certain hardness, and can just fit the insertion of an external surgical instrument, and the catheter 5 is tightly attached to the external surgical instrument in a sliding manner, so that the generation of a connection gap between the external surgical instrument and the cylindrical hole 33 is reduced.

During deflation and purification, although smoke in the abdominal cavity is gradually reduced, due to the fact that the air in the abdominal cavity is reduced, the abdominal cavity is gradually shrunken, the abdominal cavity gradually fits with the viscera of a patient, when the abdominal cavity is too close, the movable space of an external surgical instrument is easily limited, the viscera can be touched, the viscera are damaged, and in order to maintain the pressure in the abdominal cavity during deflation, new air needs to be replenished during deflation.

Specifically, as shown in fig. 1, an air injection pipe 6 is arranged on the side wall of one side of the sleeve seat 1 far away from the air outlet pipe 4, the air injection pipe 6 is connected with external air inflation equipment, and one end of the air injection pipe 6 far away from the air inflation equipment penetrates through the side wall of the sleeve seat 1 and directly stretches into the pipe wall of the sleeve 2 so as to guide air in the air inflation equipment into the abdominal cavity of a patient through the air injection pipe.

The air is guided into the abdominal cavity through the air injection pipe 6, a one-way valve and a control valve can be arranged in the air injection pipe 6, and when in air release, the air inlet speed of the air injection pipe 6 is controlled according to the air release speed, so that the air release speed and the air injection speed are kept consistent, the pressure in the abdominal cavity is kept stable, the state that smoke is discharged and inflated is achieved, the operation of a doctor is facilitated, and the air passage of the air injection pipe 6 and the air passage of the air outlet pipe 4 are two mutually independent air passages, and the two mutually independent air passages are not influenced.

The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application, the scope of which is defined by the claims. Various modifications and equivalent arrangements may be made to the present application by those skilled in the art, which modifications and equivalents are also considered to be within the scope of the present application.
