Description

A Medical Device with an Embedded Filter Module

The present invention relates to a medical device with a built-in filter module, and more particularly, to a medical device with a built-in filter module to prevent the discharge of various types of odor components, smoke, or similar foreign substances generated during surgery.

In the course of surgery, a part of the human body may be incised, and after the incision, blood vessels may be coagulated with electrical energy for hemostasis or similar purposes. In this process, smoke may be generated, and gas including various odor components generated from the inside of the human body through the incision may leak to the outside. Smoke can obscure the field of vision during surgery, and odor components can have a bad effect on the operator. Therefore, it is necessary to ensure that the gaseous component, including smoke, is discharged through a predetermined exhaust path. International Publication No. WO 2007/070570 discloses, for example, a waste collection and treatment system for collecting and treating waste materials such as body fluids generated during medical procedures in hospitals. In addition, Patent Publication No. 10-2016-0138852 discloses a harmful gas filter device of a trocar set for surgery. The gas containing smoke generated during the operation needs to have a simple structure while being discharged to the outside at the same time as it is generated. However, the prior art does not disclose a surgical instrument for removing gas containing smoke having such a structure.

The present invention is to solve the problems of the prior art and has the following objects.

Prior Art 1: International Publication No. WO 2007/070570 (Striker Corporation, published on Jun. 21, 2007) Medical/surgical smoke ejector comprising an internal sensor and a smoke filter Prior art 2: Patent Publication No. 10-2016-0138852 (Lee Byung-gap, published on Dec. 6, 2016) Noxious gas filter device for surgical trocar set

It is an object of the present invention to provide a medical device with a built-in filter module in which a filter module is disposed therein to remove various floating foreign substances generated inside the human body during a surgical procedure.

According to a suitable embodiment of the present invention, the filter module-embedded medical device includes a handle case in which an accommodating space is formed while an induction path is formed therein; a filter module into which gas containing foreign substances flowing through the induction path is introduced while being disposed inside the handle case; gas flow means disposed at the front or rear of the filter module; and at least one exhaust passage formed in the handle case and connected to the filter module to enable gas flow.

According to another suitable embodiment of the present invention, the guide path is connected with an inlet formed in the front of the handle case.

According to another suitable embodiment of the invention, the gas flow means comprises a rotating fan.

According to another suitable embodiment of the present invention, while coupled to the front of the handle case further includes a cutter for cutting or solidifying a body part.

According to another suitable embodiment of the present invention, the filter module comprises an ACF filter and a pre-processing filter.

The surgical device having an air filter function according to the present invention allows the gas containing smoke generated in the process of coagulation of the cut human body part by electrical energy such as, for example, high-frequency energy to be discharged at the same time as it is generated. Accordingly, while preventing the view from being obscured by smoke during the operation, the gas containing the smell is prevented from leaking to the outside and affecting the operator. In the surgical device according to the present invention, a filter module including a motor is coupled to the inside of the surgical device so that it is structurally simple and operates at a gas generating position at the same time as the procedure. The surgical instrument according to the present invention may be applied to various types of surgical instruments requiring gas discharge during a surgical procedure, including a pen-shaped surgical instrument for incision and coagulation, and the present invention is not limited thereby.

The medical device may be a medical device for surgery, and may have a function of incising or coagulating a body part by being put into the human body. For example, the medical device may have a function of coagulating blood vessels in the incision site by generating heat using high-frequency electric energy or ultrasonic energy for the topography of the incision site while cutting tissue inside the human body during abdominal surgery. The coagulation means may be, for example, a cutter 13 capable of incision and coagulation by application of electrical energy or ultrasonic energy, such as a Bobie Tip. The handle cases 11a and 11b may have a hollow cylinder shape or a pen shape, and may have a structure with an open front end.

Electrical energy or ultrasonic energy may be transmitted to the cutter 13 , and a blood vessel or a body part similar thereto may be incised or coagulated by the cutter 13 . In addition, odor components, smoke, or similar foreign substances may be generated during such incision or coagulation process. As described above, the odor component or smoke generated inside the human body during the operation may have a bad effect on the operator or assistant while containing harmful substances. Therefore, it is necessary that the gas containing smoke or odor be discharged to the outside in a way that does not affect the surgical procedure. Such a gas is advantageously induced along a closed guiding path while being induced to the outside immediately after being generated. To this end, the gas may be guided to the outside through a separately installed suction means to be treated. However, when a separate suction means is installed, there is a disadvantage that the surgical space may be narrowed as the apparatus for surgery becomes complicated.

It can be introduced through the guiding path 17 formed along the inside of the handle cases 11a and 11b and guided to the filter module 14 . As the gas flows along the filter module 14 , smoke components, odor components, or similar foreign substances may be removed. In addition, the gas from which foreign substances are removed while passing through the filter module 14 may be discharged through the discharge passages 18a and 18b disposed at the rear of the handle case 11 . The filter module 14 may consist of a plurality of filter layers, and gas flow means 15a and 15b may be installed in front or behind the filter module 14 .
