Description

ENDOSCOPIC SUTURE DEVICE WITH CIRCULAR NEEDLE

Technical Field

The invention relates to suture devices that are used for bonding the tissues with one another in endoscopic operations.

The invention more specifically relates to a suture device that provides the bonding of the tissues from one point with minimum damage by enabling circular movement of its needle, which has a special semi-circular form and is attached to the thread, by the virtue of cylinder system in all closed operations including laparoscopic and thoracoscopic operations.

Prior Art

Suturing the tissue in endoscopic operations that are performed in a closed manner such as ventral cavity and thoracic cavity is an application that is widely used in prior art. In these kind of operations, which are also called laparoscopic and thoracoscopic operations, there is a need for methods and devices that are invasive in minimum and that do not damage the tissues. Various tools and devices are used for this purpose in prior art.

An example of suture device is presented in the utility model document titled "Magnet needle holder" which is registered as TR2006/06331 in TPI. The device is used by inserting into ventral cavity through a pipe of 5 mm diameter, needle is captured by jaws via a magnet that is placed on the top of the needle of surgical thread that is inserted into ventral cavity via another pipe and the needle is used in the suturing by compressing the needle inside the mechanism. In this application, the suturing process is done by another device after inserting the body. Therefore, it is needed to perform two openings into the body and to use different equipment.

Another device that is used and designed for the purpose of endoscopic operations is described in the patent document titled "A surgical tool" with number TR2013/01275. The said invention is a surgical tool that includes handles enabling the handling of the tool by hand and fingers of the user and fixing the tool into the hand in endoscopic method, a needle handler enabling the ease of movement and stabilization of the needle when carrying, a indented surface enabling locking in order to limit the undesired movement of the drive part. With this design it is aimed that the undesired movements are the detachment of the needle from the needle handler during the endoscopic intervention. Nevertheless, the movement of the needle still largely depends on the hand the machinery accuracy cannot be benefited from.

Device that is described in the USA patent document titled 'Ventral hernia defect closure' with number US2016354192 has a similar structure that resembles to the two jawed tools being used traditionally in the technique. In this structure, the needle wherein a thread is inserted between two ends parallel to each other, performs serial transition procedure and it has to perform insertion to the opposite side for each tissue transition step by staying connected to one of the ends each time. Therefore, suturing can be performed with two process instead of one and the tissue is damaged more than desired. Consequently, recovery time of the patient is getting longer.

In the structures titled 'Endoscopic sewing device and associated method" with number US7842046; 'Placing sutures' with number US9504465, 'Suturing instrument with deflectable head' with number US2007088372; 'Endoscopic suturing device with suture management' with number US2012022560; 'Endoscopic Needle Assembly' with number US2012150200; 'Endoscopic suturing device' with number US2012029536 in USA patents; needle moves along one route, an insertion on the opposite side is required for each tissue transference and abovementioned problems occur.

As a result, a need for a suture device that provides the bonding of the tissues from one point with minimum damage by enabling a circular movement of its needle, which has a special semi- circular form and is attached to the thread, by the virtue of cylinder system in all closed operations including laparoscopic and thoracoscopic operations and the inadequacy of the existing solutions entails an improvement in the technical field.

Purpose of the Invention

The present invention relates to a suture device that fulfills the abovementioned needs, eliminates the abovementioned disadvantages and provides some additional advantages.

The main purpose of the suture device according to the invention is to provide suturing the respective tissues with one move with circular movements by enabling the circular movement of the needle, which has special semi-circular form that is connected to the thread, by the cylinder system. Therefore, additional devices are not needed to be used and the operation can be performed with one entry point that is opened into body. Consequently, it is possible for the operation to affect the patient in minimum level by enabling the insertion from one cut point. Thread, needle and the mechanism that performs the suturing are integrated in one device and it does not have risks as other applications do, such as needles not contacting with the magnets, jaw locking mechanism having a loss of function when inside the body and being opened and losing its function of handling the needle. The possibility of damaging the organs by losing the needle inside the body is decreased to the minimum level.

Another aim of the invention is to prevent the detachment of the special designed needle from the device by protecting the needle in a fixed position in the movement channel, which is located in the device in an integrated manner. Due to the shape of the needle and its obligatory route that the needle follows during the suturing and it is fixed to the control area of the device; even in case of an undesired movement, it is not possible that the needle is detached from the device.

Another aim of the present invention is to perform the desired suturing process with one movement of the needle due to the needle movement occurring along a circular route. Therefore, it is enabled that the needle harms the tissue to be sutured in minimum level during the suturing and the healing of the patient after the operation improves at the same rate.

Another aim of the present invention is that the needle has the ability of moving bidirectionally within the movement channel and provide ease in the operation with this movement freeness.

Another aim of the present invention is that the needle can be located in an angular manner with respect to the body and provides movement freeness due to the juncture structure of the suturing module in which the needle bearing is located.

Another aim of the present invention is that the thread is connected to the needle in a fixed manner by compressing during the production and therefore a need of needles being connected to threads before the operation is eliminated. Thus, time is saved during the operations.

In order to achieve the abovementioned goals in general terms, a suture device is developed that performs the bonding of the tissues from one point with minimum damage by using thread in all closed operations including laparoscopic and thoracoscopic operations and that is being moved by an actuator connected to the body. The developed suture device includes at least one needle shaped in a manner to form a semi-circle and including at least one pointed end and that is connected to the thread, at least one movement channel that guides the movement of the needle by taking the movement axis of the needle as center, plurality of cylinders that align around the movement channel, being moved by at least one actuator and enables the needle move in the respective direction within the movement channel by contacting it, and at least one needle bearing beds the cylinders. The structural and characteristic features and all advantages of the invention shall be better understood by the Figures and the detailed description that refers to these Figures provided below, therefore the invention shall be evaluated by taking these figures and the detailed description into account.

Detailed Description of the Invention

With the invention, a suture device (10) is developed that performs the bonding of the tissues from one point with minimum damage by using a thread (50) in all closed operations, including laparoscopic and thoracoscopic operations, and that is moved by an actuator (35) that is connected to a body (20). Different from the known applications, the suture device (10) comprises at least one needle (41 ) shaped in a manner to form a semi-circle and including at least one pointed end (41 a) and that is connected to the thread (50), at least one movement channel (42) that guides the movement of the needle (41 ) by taking the movement axis (x) as center, plurality of cylinders (43) that align around the movement channel (42) and being moved by at least one actuator (35) and enables the needle (41 ) move in the respective direction within the movement channel (42) by contacting it, and at least one needle bearing (44) that beds the cylinders (43).

In Figure 1 and 2, top and bottom views of the suture device (10) are provided respectively. A handle (30) enabling the handling takes place on one side of the linear long body (20) while on the other side the suturing module (40) protecting the needle bearing (44) is located. The suture device (10) is controlled by handling the handle (30), it reaches to the operation area with body (20) and suturing is performed by suturing module (40). A juncture (21 ), which is shown in Figure 4 and of which the details are provided in figure 5, enables the connection between the body (20) and suturing module (40), naturally between the body (20) and needle bearing (44). In addition, the juncture (21 ) enables the rotating movement of the needle (41 ) with respect to the body (20).

In a preferred embodiment, the actuator (35) is an electric motor and operates with the energy supplied by a power source (33). The power source (33) can be a cable fed by an outer source as well as it can be battery type energy storage. A control unit (34) which regulates the functions of the actuator (35) is located in the handle (30) in preferred embodiment and it is managed by a control panel (31 ) formed on the handle (30). An indicator (32), which is in screen form, enables monitoring the data that comes from the control unit (34) or goes to the control unit (34).

In Figure 3, a side section view of the suture device (10) is given. The movement transmission from the actuator (35) is performed by the drive shaft (36) along the body (20). A reductor (37) that is located between the actuator (35) and the drive shaft (36) aims regulating the movement and providing it on the desired level.

A perspective view of the suturing module (40) is given in Figure 6. The circular form of the movement channel (42) is centered in the same rotating axis (x) with the needle (41 ). Thus, needle (41 ) can move bidirectionally in the same route without convulsion. A chassis (45) that is located in the suturing module (40) and is composed of two parts, mediates the connection between the drive shaft (36) and needle bearing (44). As seen in Figure 7, the movement channel (42) is located between the needle bearings (44) that are located in parallel to each other and it is surrounded by the cylinders (43).

The top section views of the needle bearing (44) are provided in Figure 8a and 8b, when the needle (41 ) is in different positions. A side section view is given in Figure 9. The needle (41 ) enters into the movement channel (42) from one point and exits from it from another point while it rotates in the rotating axis (x). Suturing is performed with the thread (50) that is connected in this manner. In Figure 10, views of the needle (41 ) from different angles are provided. In the preferred embodiment, pointed ends (41 a) are formed in both ends of the needle (41 ) and a connection point (41 b), which helps the connection of the thread (50), is located on the needle (41 ) as shown in detail in Figure 12. As it can be seen in Figure 1 1 , the needle (41 ) is composed of two identical parts that are symmetrical with respect to the folding axis (y).

In the preferred embodiment, the needle (41 ) has a special production process. The process flow chart can be seen in Figure 13. Here, in the first process step, two needle (41 ) forms that are symmetrical with respect to the folding axis (y) are cut (A) from the sheet metal plate with the help of a cutting template (60) and afterwards symmetric needle (41 ) forms are bent (B) with the help of bending template (70) upon the folding axis (y). Cutting template (60) has two parts and it performs the cutting (A) process by pressing the raw materials stainless steel sheet metal or titanium series etc. in the production. After cutting (A), needle (41 ) with two-winged form, which are symmetrical with respect to the folding axis (y), exits the cutting template (60) as intermediate product, is passed to the second stage. In the second stage, bending template (70) makes the needle (41 ) with two-winged form double layered by bending (B) it on the folding axis (y) that is located in the center of the structure. Before the bending (B) step, thread (50) is located between the sheet metal and the bending continues until the desired pressure is applied. In the last step, folded needle (41 ) forms are crushed (C) with the help of crushing template (80) and the final form is obtained. In the crushing (C) step, a pressure that is higher than the bending (B) step is applied. The crushing (C) step is a process that enables the needle (41 ) to be seen as one piece and to have high endurance. The process is also called ironing. All side edges of the needle (41 ) are softened and the pointed ends (41 a) become sharper. At the same time, the fixation of the thread (50) to the needle (41 ) becomes clear during crushing (C) stage. It is designed that both ends of the final product needle (41 ) has pointed ends (41 a). It is designed that the middle part of the needle (41 ) shall be circular and thick and the thread (50) is fixed to the middle part of the connection point (41 b) of the needle (41 ). This way, needle (41 ) obtains the ability to move bidirectionally along the same rotating axis (x) (both clockwise and counter clockwise directions).

In the present invention, the needle (41 ) performs the semi-circle movement that all the surgeons are familiar with. The most distinguishing feature of the present invention is that the needle (41 ) with special form design operates in a manner that it can move along the cylinder (43) system and it has the thread (50) handling angle. The needle (41 ) that is used in the suture device (10) is described visually and it is designed in compliance with its geometrical lines. The needle (41 ) is an auxiliary element aiming to perform processes such as cutting and inserting and its production material is determined as stainless steel sheet metal of 316 L series. Nevertheless, different metals such as titanium series can also be used.

The operation principle of the suture device (10) is determined by the software loaded to the control unit (34) which is in the circuit card form. The operating modes of the suture device (10) on the indicator (32) that is located on the control unit (34) are determined by the control panel (31 ) that is also located on the control unit (34). These movements can be guided via the buttons that are located on the control panel (31 ). The suturing module (40) has the ability to perform a rotating movement of 45° to both directions. The actuator (35) with reductor (37) is the drive source and it is connected to the suturing module (40) thanks to the drive shaft (36) that is located in the between. There are small metal cylinders (43) which provide the circular movement to the needle (41 ). Suturing process is performed by the virtue of the circular movement of the needle (41 ) that is located on the suturing module (40). Cylinders (43) take the movement from the drive shaft (36) that is connected to the actuator (35) and they are positioned with the needle bearing (44) in a manner that they cover the surface of the needle (41 ) completely. During the circular movement, needle (41 ) always stays within the movement channel (42) which is located in the active area of the cylinders (43) and therefore the continuation of the circular movement is obtained. The outer line of the needle (41 ) forms a complete circle. This is a requirement for obtaining the compliance with the movement channel (42). The control unit (34) includes a processor. 8 bit to 32 bit processors can be used upon the control unit (34). The indicator (32) can be used as tft or glcd, as desired. The actuator (35) can be optionally used with brush or without brush and as servo motor or step motor. The body (20) and the handle (30) and all the other parts can be plastic as well as they can be manufactured from stainless metal material. The suture device (1 0) can also be operated with computer controlled (USB, Bluetooth, Wi-Fi, etc.) when desired. The invention as it is, is used for the rapid suturing of the live tissues from one point and minimum damage in the operations that are performed with endoscopic surgical interventions.
